TRANSCRIPT Ð 3D Printing and More All right, it is 30'clock. Welcome everyone. Glad you could join us for tea time this week. Hope you've gotten your tea or coffee or preferred beverage for 30'clock. And ready to start our session. Just a reminder if you could please make sure your name is showing and not and just an initial or an iPhone or an iPad. It looks like just about everybody is good. But I'm not seeing everybody in the in the participation just yet. Okay. All right. Today our topic is going to be with Mr. Jim Allen, O and M and he's gonna talk to us about. 3D printing and more woohoo so excited You have. Yeah, but before we hand over the mic and everything to him, we're gonna review our goals and our meeting norms. Our goal for T time is to build a community of practice for technology and support each other. As we're teaching technology to our students when we're you know, far flung in our local district. So in the spirit of that goal, we want an interactive session. Where you're engaged and asking questions if you don't feel comfortable unmuting yourself. Thank you. You can put that in the chat. By registering for this session, you've given us permission. To record and post. This will be posted on our website for later viewing by other professionals. And. No, it's before we start to get the stuff up, what you do. Tax key time is an We are. We published that on the website and in my website and live binder after the session. So welcome to everybody. Let's go over here if you feel like speaking in that. Theme. Please, please, please ask a question. If you're too shy now there can't be any of us out there that are too shy. I know most of this group. We can. Talk out loud and ask those questions. Please speak your name first so that we know who we're talking to. There's a large group and it's very hard sometimes to see who is speaking. Alright, so I'm going to stop my share and hand things over to Jim. Yeah. For the hour. Yeah. Okay. It's been a while since I've done a zoom presentation. So I see that we've got a bunch of us here like almost 30. I can't do a show of hands and I couldn't find the poll app, but if you could put in your chat. Or good feel like yelling out, how many of you are O and M's? Or dual certified. Either one, yeah. I saw a couple of hand waves and things going on. Okay, so do we get an answer yet? Do you have any idea Donna? Through chat. Yes, we've got a lot. I'm sorry, I was muted. I was just talking on out and I was muted. Yeah. Yeah. We've got a Laurie, Anna, our own M, Amanda's duel, another, another Laurie is dual. She is O and M. I'm sorry, we. So a good, like maybe half of you, that'll. That'll work just as an idea. We've got quite a few. Okay. Yeah, so I've been in the field for a really long time. And, been at the school for A bunch of that time and we have many threed printers at our school and I think they're popping up. All over. So if you don't have a maker group in your community, you might check with your. Sure. That's real arts people at the high school. A lot of libraries have them. Public libraries have them. And most of what we're gonna talk about is readily available. On the. On the web, a little bit of Googling will find your almost anything you need. And, let's just start with what is 3D printing. And what is a makers group, Jim? Sorry, I'm some of our, some of our groups may not know. Oh, Oh, we'll have this conversation. So a makers group is is people who like to make things and it doesn't matter if it's with a threed printer or it's woodworking or it's welders or electronics. They just love to make things and you might even get into some arts and craft stuff. And The community in general is very helpful and they will help you do whatever you need to do. Or, tell you where you can find the, you know, equipment you need or someone who has the expertise that you need. And I'm not sure how you actually go about finding them, but I know they're just, they're all over. So, feel free to chat a question or, Raise a hand, I guess Donna will call or just talk out will answer whatever questions we can find. Got a Brailas too. Cool. So a 3 day printer, let's start with that is. Okay. A machine. That creates a 3 dimensional object. Using a layered additive process. And you're all going and what is that? That just so. Think of it as. Let's see, wet spaghetti. Let's do that. So we take our wet spaghetti and we lay down one and make a circle out of it. Then we take another piece of wet spaghetti and we lay it down on top. And the 2 pieces of spaghetti stick together. Then we add another piece of spaghetti. And eventually we will build up. The cylinder. 3D printing works pretty much the same way. You buy these schools of Go, filament made out of plastics like a big a giant school of thread. Of plastic thread that, weighs anywhere from a pound to 2 pounds. And you plug it in to a little. Device. That melts the plastic and squirts it out of a tea tiny little hole. And it's got motors attached to it and it drives it all around. And as it makes those layers of what we talked about earlier, the spaghetti. It's slowly raises up. So it doesn't keep printing the same layer over and over again. So it prints one layer and it goes up. I teeny little bit and then goes up a teeny little bit and each time it prints another layer of clastic in the outline. Of whatever it is you're making. And these things are amazingly accurate. The printers we have at school. Can print at. God, what is that? It's 5 one hundredths of a millimeter. Usually I print it. 2 tenths of a millimeter. Which makes. Pretty darn nice. Objects that we want to make. I've got a picture of one here. Let me share the screen. And here's a. A vase in process. So this is the printhead. This is a fan on the front. The filament comes down through the top. It gets melted. And there's a little motor. That keeps grabbing the thread and pushing it into the hole. And eventually it comes out way down here in this little point. And it will trace. The shape of this. Base. So all these little outside ripples and inside ripples, it will do each one. And this looks like it's a couple of millimeters thick and so it will do depending on what you choose, it will fill it in solid. Or it'll fill it in with the honeycomb process. And each time it makes a layer. It raises it up another whatever your setting is, you know, 2 tenths of a millimeter. And eventually, so as you can, you know, think about that 2 tons of a millimeter, so it takes 5 trips around to make 1 high. It takes 25 to make an inch. So these things aren't fast. You know, if you're going, oh, I need something in 10Â min, it's not going to happen. An average depends on what you're making. But, I don't know if you guys, How many of you have seen? The, just second. Get your faces back here. How many have you seen the, Brow writer finger guides. At the school or seeing people talking about them. They're a thing that slides into the, Braille printer. Keeps your finger separate so the kids get proper. Trail rider technique. I have files for those. We give them away at the school. By, you know, we have boxes of them that we make. They take 3 and a half hours a pop. To me. So It's, you know, not a fast process, but the thing that's fantastically amazing about them that you can make anything you want. When we were installing or getting the printers, we needed a, an outlet for an ethernet cable. But I couldn't find one. So I went online and. Found the file for it and just printed one. And that took about 2Â h and then I had my instant wall plight. To plug in my printer to. So it is that makes sense so far. Anybody have unclear on anything? Oh, I good. I got a thumbs up. Cause I saw some people going. Yeah, I sort of got it. And we have a question what type of file. And White can. Hmm. What type of file is it? Yeah, excellent question. So it's called, there's several different kinds of file types. But the one you usually that I, when I do a Google search on, I use STL. Which stands for a stereo lithograph. And when you, get some. File. Or you create them, you can. You get this STL file. And then you run it through another tool that's also free called a slicer. Usually a slicer comes with the any type of printer that you have. So we have 4 different kinds of printers. So we have 4 different slicers. And what that does is converts. This particular image. It slices it up into little triangles. Thousands and thousands and thousands of triangles. And then creates the directions. For what the 3D printer is supposed to do. So the 3D printer has an X and a Y access so the head moves. Forwards and backwards and it moves left and right. And then the whole thing moves up and down and but a combination of all of those move directions you know you can make a circle You can make whatever shape you want. And. Let's see what else is there. How many of anybody used a 3D printer? She says no up. Jane says yes. Okay. No, all right, so. Okay. Well, so did. Donna, did they get the handout? I sent you yesterday. I will link it right now. Oh, right. I have it in my notes to link as soon as you were ready. So I know this can be one of those things that will. Blow your hair back, so I'm trying to keep it. Fairly simple. I hope I'm not being. Too pedantic. But feel free to ask any questions. You might have. So one of the things that Donna and I talked about was doing this, talking about O and M. And one of the things we've. Developed at the school. So some kids don't have the hand strength. To take a folding cane and twist the elastic around it. And they just can't seem to manage that. So one of the things we made, let me share my screen again here. Is the cane tab. And so this is. Our 3D, one of the 3D printing softwares we used. And. As you can see, I hope that comes through. This is big enough to. Stick your fingers into and it's sturdy enough. To. The elastic for the cane goes through this little gap here and then the kid can stick their hand. Through the hall and give it a twist and loop it around the cane. If they need. So with this software, you can zoom in and see. Exactly what's happening. You can rotate it. And you can see how long it will take to print. And. Lots and lots of other things. The, the thing when the first time We got a 3D printer. And I printed something out. The thing that blew me away was how absolutely amazing it was. I probably stood there, Sue O'brien and anybody else who happened to walk by. You just stand there with your mouth hanging open. As something is created out of nothing. On this bed of the printer and you almost have to keep yourself from drooling. It's just so amazing. To see something just appear. And You keep watching it and watching it. It's like, okay, I've got to do something else. I must walk away in order to let it do its thing. And, unfortunately that's a couple of hours or in the case of when we printed, half of a moon we were going to print out the full globe with the moon with craters and mountains and whatever. That was 24Â HA hemisphere. And so, you know. You. You have to wait a bit sometimes and it's not always easy. And then of course, there were other things we printed. Cause these are fairly sensitive machines. That and the kids are wild about them. They love to they make all kinds of really interesting noises. But also if you bump the table. It might. Shift. The head just a little bit and there have been other times when I've come back in the morning and I just have a giant ball of spaghetti filament. Because something messed up and it no longer kept on track and there was nothing underneath it. So it was just spewing plastic out. Into the air and made this giant, bowl of spaghetti. Yeah. Pam, this is Donna. Jane says she loves the cane cord twister and asked if you used PLA and where the file could be found. Yeah, I will. I'll give you the file. I'm trying to remember if I put it up on thingy verse, which is another thing. Yes. So you use plastic And. PLA stands for Polyactic Acid. It's. What do you call it? And it will break down in the sun and dissolve. And there's many, many, many different kinds of plastic. You can print with nylon. You get filaments in pretty much any color. You could imagine you can get them in metallic. I mean the gold stuff we printed out an Oscar that's absolutely stunning. And it was done in gold filament. And, it's at the, you know, if you ever stop by the school. You can. See it there. But it was, it was beautiful. And, we printed out another one and gave it to the superintendent. And I think she has it on her desk. Oh. Yeah, I went ahead and shared the thing averse link, but if it is to the street intersections, but that will get them to think of us at least. Okay. Okay. Yes, so thinking verse is a wonderful place. Where you can go to find. Nearly anything you can think of. So, you know, you think, well, I need you know, for math class or whatever I need. The You, Euclidean, what are they? The solids, the basic, you know, your cube, your pyramid, your. I can't even remember what all the names of them are. You can find those online and with a click of a button and you know. 5, 6Â h, it just prints out. So if your teacher needs a model of something, we had a teacher say, Oh, you know, we're studying. The French Revolution. Everyone wants to know what a guillotine is. I've tried to describe it, but they don't get it. Can you, you know, make me one? It's like, okay, we'll have one tomorrow. So we went online to Thingy verse, typed in guillotine and there was one and so it's like, yeah, that'll do. We didn't, you know, weren't sure what they wanted. So we printed it out. And then the teacher came back and says, Well, it doesn't work. Do you have one that works? So that was a bit more searching around to find a guillotine that had a moving blade. And so. And we had some question comes in. Oh, sorry, Jim. No, so that was, you know, so it's. It's a fun thing to go hunting around to find. Whatever it is you're looking for. Yes, question. So this is Donna. I'm asking for Alicia. She says does do you have any of the finished chord holders that they could see? And then, Elise, Ashley asked what program do you use to create the objects? Can you walk them through the steps to create something from scratch? I think that might be a whole another course. That might be a whole another car. So to see what it would look like when it prints out. That's what it looks like right there. I, are. You'll need to share again. Oh yeah, of course. Thank you. Share screen. That screen. Share it there. So this is exactly what it looks like. And this is something I designed with the input. It was actually our OT. He, Roger Toy, who also came up with the Braille writer finger guide. He brought this thing made out of foam and tongue depresser blades. And said, can you make this? And it's like. What is it? And he says, and he showed me that it, you know, slid into the brow rider and what it was supposed to do and I said yeah we can do that so I designed it. This is. Also a simple design. But let's go to, see if I can pull up that tool. I can make it work. Yeah. Hello. And they also asked this is Donna again if you had photos of the Braille writer guide. I can look for that one while you're, while you're doing the other one. Sure. Yeah, what was that? Oh. Yeah, there's a wonderful little tool. Called, Tinker CAD. See if I can bring it up here. It's 3D modeling software. It works. Are you seeing the screen? We're still seeing the, This the picture of the folder. Oh, something else. Okay, well, let me see if I can log in so you don't have to watch me. Login. Yeah. We've got your cure up, but that's. It's just the static picture of Kira. There. There, okay, let me, let me find my zoom. Oh, okay. You are sharing. Okay, can I change screens? No, let me, I guess I'll have to stop sharing. And then re-share. And where? Did it go? Okay, here's. Tinker can. This is free software on there's a Braille writer finger guide. We'll go look at that. And I just shared the thing averse. Finger guide that has a picture of it on a Braille rider. Okay, oh, perfect. So, and this, this is my workshop. It went through. Oh. It doesn't 2 dozen. Iterations. Before I. Came up with the design that we have now. That I that I finally. Light. When I first made it, it didn't have the curve top. And they said, no, we don't want square edges. And then it, you know, it kept breaking so we, curved. The blades a little bit to make them sturdier. And then we change the bottom so that it would print better and You know, and these are all my ideas and and bits and pieces of what I started with. So essentially, We. Let me just move this out of the way. And you have these things that are called primitive. So here's a box. We're gonna drag it over. Is this big enough for you all to see? You're doing. There. Do I just drag? Yes, go ahead. Jane says that the brow rider finger guides are their most requested items that they love them. Yay! And I need to put the new improved one up. Because it it prints much cleaner. And you don't have clean up. As much cleanup or sanding to do when it's done. So the process of making that like to make the base. You can see one here in the background. You know, I started with a little box and it says it's 20 on the side and I said, no, I only want it. 10 high or. But I think it was 8 high. 7 9 high there. And then I can drag it. And I can make it long. And then. I can get another one. And what I did was made it. Really skinny. And then I made it tall. Right, and then you drag it over. And stick it in place and then when you turn it around and look at it you go oh it's just sticking out the wrong way and so you scooch it in a little bit. And you just fiddle and fiddle. It's amazing how many hours. You can just sort of fritter away while you try and get everything right. So if you have any. Ocd tendencies. Be prepared to spend some time getting everything absolutely right. There's. All kinds of interesting tools and things you can do with this. And once you're done. You just, exported. There's an export tool, yeah. There's an export tool. And it saves it. As there's your good old STL file. And then you run the STL file through your slicer. And which is. You know, in our case was the Kura. And it shows you the picture of what it's gonna look like when it's done. And then. You wait 3 and a half hours and you get one of these green things here or whatever color you printed it out as. I also have one if you have the electric brailer. Is slightly different. It's smaller in size. And I have one for the electric Perkins also. So that's, Tinker CAD free accounts. Design away you have all these tools. And since we were talking about the. Let's see, where did I put them? Oh, it's not on the screen. Okay. I created a whole bunch of the. Intersection parts and we'll go. Next. So I'm going to close this window. Now what are you guys looking at? The Tinker CAD search page. Oh yeah, okay. So hopefully it stays here on the. In the browser. So another place that, well here's Tinker CAD. And which one did you pop up? But doesn't matter. We'll go to this one. This is in your handout. This is. Braille and large print. Services based out of Sydney, Australia. And they created. All of these pictures. So here's the math for. Pythagoras theorem. And it's interesting a lot of these things you can find in APH educational materials or you can Find them here and print them out. This is, electrical circuit diagrams. You can. Make your own bits there. Now notice that in this one, the electrical circuits that's printed in black. And the. The circuit parts are in yellow or green. Whatever color that is. You can make your printer print multiple colors. It's a bit of a hassle. I suggest getting some acrylic paint, which works really well. And I would probably paint this, you know, do this all in black. And then get a. Acrylic yellow paint pen. And then draw over the bits that are raised. And, this way you make something that's useful for your low vision kids and your, and your Braille kids too. And I linked the acrylic paint in the chat. It's also in here. Yeah, and yeah, I found the tried to find the basic crayon box of colors. For acrylic paint. And came close. It's in the handouts. So here's a spectrum. And let's see if I can zoom in on that. Well, here we go. Let's do this picture. Cause there's something I want you to see here. That's, so each color. Is done in a different texture. And this was all done. Looks like it was probably done in Tinker CAD. Because these are all shapes I recognize. So you get a different texture. And they also labeled it. In Braille. So you can do Braille on a 3D printer. But you have to print it a certain way in order for it to come out properly. So this is done. In. So it's printed just like it's shown. Let's see, how do I describe this? So. Usually you let me get, let me stop sharing so I can see what my hands are doing. Get my picture here. Okay. So when you print, you have the print bed. And if you print the Braille on it. It's gonna make a series of little pancakes. And it will raise it up, you know, half a millimeter. And that series of pancakes will have really sharp edges on it. And it'll shred your fingers as you try and read it across. So what you have to do is Put your print your braille vertically so that the braille comes out. From my hand on the edge of the thing. So it gets it'll get curved and smoother that way. Because that it's you have all these people who say, oh, here's a great rail font you can use in whatever Braille or design software you're using. And generally it always makes those pancakes. Even if you put little, you know, say I'm gonna use a dome object, it still will print out pancakes because 3D printers don't do well. Printing things that are curved that are really small in a vertical. Wait, if you do it in the horizontal surface. Or, you know, this way. It will print out. Much, much cleaner. So let me share that screen back again. I hope that's making sense. That's definitely a good thing to remember if you're using any of your maker groups who want to make something for you. Yes. Is to make sure that they get their file turned. So that it prints in the right direction. And so. So this, thing, the Prism was. Printed just as you see it. So you're, you know. It was printed vertically like the monitor on your computer and the Braille is poking out from your monitor at you. That makes good clean braille. I generally recommend if you have, the, The Braille on paper or the Braille label paper. Or a dynamo labeler. That adhesive is pretty good. And it's faster, cleaner, easier. To do it on a rail writer or a dynamo labeler and cut it out and stick it on than it is to get the Braille right and the spacing and to fuss with the printing. Well, let's see what else they had here. So. This is how Braille usually turns out. These are actually. Alphabet stamps, so you want them to be flat. But they were printed. You know, parallel to the print bed, which is why you get these nice Clean circles and you can imagine trying to run your finger over the edge and, or trying to read the Braille. And it, you know, making a mess of your fingertips. There were a couple of other things in here. Oh, there's a kidney. Volcano. This is frog with parts. So. I love the frog. I have a frog. It is my favor. And it's not as easy as it looks to put all the pieces back together. It is not. Oh, and this was Donna, by the way. Just chiming in on that frog. Oh, clever. Yeah. And, you know, so if you need a protractor, you can. My frog actually is smiling when you flip it upside down. It's a little makob. Print one out. Oh, there's a brow rider finger guide. There you go. So you can see what it does and keeps the kids from mashing fingers together and you know, or shifting fingers. Wish we had this for a standard typewriter and keep the kids from. Doing 2 finger typing everywhere. There's a Curiosity Rover. So you can see pretty much anything. You might think of needing. In any of your subjects. You can create, oh, yeah, game playing dice. And fossils. So. We'll leave that be. See, is this my? Street intersections. Yay. So this is another one that's in your handout. And these were done. So there's a group of us, 3D enthusiasts. That get together there's a an anzac group which is Australia, New Zealand. And parts of the South Pacific. That get together, once a month. To and they're all tvi's or OS And they. Make 3D things and we talk about issues and whatnot. And so here is a. A street intersection. That you can build and there's Hearts available. So each one of these plates. You can see that there's. A line down the middle of Each thing, that boy, that didn't make any sense at all. My apologies. So there's a base plate and you take 4 of them together. And it will make a hundred centimeter Or 100 excuse me. . Square. Tim, this is Donna. Can you assume out just a little bit? Yep, let me. That's a little better. There we go. There we go. Okay. So each is an individual piece. Well, let me bring one up here. Here's one. And so you put 4 of them together, you get an intersection. And that's the roadbed. Then this brave bit here is the land as it were and there's a curve up so you get your you know real curve. There's 2 or 3 different kinds of these. For depending on the corner. This is the big wide corner ramp, but there's also the individual, you know, the, whatever it is, the 4 foot wide to 6 foot wide one. That you see on most streets. That doesn't take up the whole corner. There's grass that you can move around and put where you want so you know define the sidewalk. You can put the fence in. And, also the crosswalks you can see that, This one, they took a lot of time printing. Or no, this is just a diagram. So the crosswalks are separate and you can drop them in wherever you want and there's Just the lines, there's also the zebra. Pressure. And if you want, oh, here's. Here's one that's got the, you know, the ramps that go across the street. And if you have a really good monitor, you can see that there's crosswalk lines there. So this is a different kind of. RAM in the street. And you can also get them with, traffic islands. And you know pedestrian pauses on the corner. With the traffic circle. And these are all to the same scale and you can mix and match and draw. Or make these however you want. And create that one troublesome intersection that, you know, some student might have issues with. And it will all fit in a. We built a little frame. That you could just drop them in so that would all fit in a little bag. And then, you could pull them out on the street or review it before you get to the street. And, then talk about what the different parts are and. You know, proceed with the lesson that way. It's a pretty, slick. Set of tools. And all of these are Tinker CAD bits. So you can pull them out. Open up Tinker CAD and drag the bits around and align them and make whatever intersection you want. Yeah. That's awesome. You know, I love the intersection one. Was there a picture on the last page of other items that could go in the intersection one. Was there a picture on the last page of other items that could go in the intersections? Like people and Thing Oh yes, Yeah. Let me find it here. Here we go. This one. So here's the. Let's see, zoom in a little bit. Right it down. So we've got. Variously a city bus. We got some cars, you know, here's the. The island with the. Pedestrian pause as they call it in Australia. Traffic lights. Bicycles, various people. Various signage. They can go in there. And when, Leona started doing this, there were all kinds of, oh, can we ever this? Can we ever that? And so she's made. Various buildings and other sorts of things in another collection. Churches and houses and How's with garages and that sort of thing. And then she's done some research on this too that she's working on getting published. And this is another one that somebody else did. That was. Like puzzle pieces. And these are these are fairly thick. There. Oops, I think I need to zoom out again, don't I? There. There. I don't know. About 3 quarters of an inch thick so that the pegs and the, you know, so they fit together like tinker toys. And here's an example of things so you can build long streets and intersection if you have enough of them you can probably print out a you know, a neighborhood. So that you could. Before. And Ashley, oh sorry, Jim, Ashley is asking if they're all free to download on Thing averse. They are. Anything on thingy versus free. Now these will take you a bit. I've printed these and they were. This is, I think, whatever the metric measurement is, but, you know, 3 inches by 3 inches. Thereabouts and each one takes about 4Â h to print because they're so thick. So this is. Can you fit multiple on a plate? For those Jim or should you just do one at a time? Yeah. And, and then the time, yeah, you can fit, depending on the size of your printer, you can fit multiples on a plate. But then your time. You know, if you put 4 on a plate, you're 4 times a time. And the. The consequence of error is that you. Muffed up 4 of them. Okay. Anytime you leave it. Unwatched. I mean, the most of the printers have a little camera on it. So that you can watch it. And when you see it, start spewing stuff. If you have a wireless connection to it, you can tell it to stop and bone. And then you scrape it off all into the trash can. Cause there's not a lot of backing up if it messes up. And then here's. As long as you haven't fallen asleep, sorry, this Donna, as long as you haven't fallen asleep when the camera goes off. And so here's, you know, the. Traffic islands and cul-de-sacs and. For those of us who live in Austin and other places, the traffic calming things so that the cars can't go flying down the street. And crosswalks and then 2 lane roads with medians and you know. All kind of stuff. So that's, so we're like 3 45. Are there, I wanna. Pause for Questions? Oh, there's Why someone? This is Donna I was reading now Ashley's she says that have they created any maps for indoor building layouts. Yeah, okay, so here's the thing. So you got you know, when you have a 3D printer everything should be 3D printed And if I were doing interior. Building, I would probably use swell paper. One, it's a lot faster. And to print out a you know the picture of a room or the hallway with the doors and whatever. You know, you could whip up something, you know. Your time and word would be. You know, an hour, whatever drawing program you're going to use or not even that much. And then you print it out and 20Â s later you've got your swell paper. To draw it out and get it looking right with Tinker CAD and then. Downloading it. Doing getting the STL file. And when you print it, it's gonna take you 6Â h. Or more. Because you're gonna do, you know, as a 6 by 6 or 7 inch by 7 inch sort of thing. So that you can. The student can. Get an overview of it. And that, you know. That's seems like a lot of time for maybe a one off. Where swell paper is. One and done and it's ready when you need it and it's easy to modify. Which brings me up another point. Things with 3D printers. Can be amazingly visually detailed. To the point where it's like, that's just, you know, absolutely stunning what the detail you can see. But you can't necessarily feel that or if you if you can. Feel the difference in the texture and things, you don't really know what it is. So you have to make things, you have to realize that your I can see. Incredibly, incredibly fine detail. But for a student. It's you gotta have. The finger. I mean this is their pixel. Right? If they can't get their finger in it. They can't see it. And it not just that you can touch the thing, you have to be able to move your finger so you need space in order for them to move it around. So I've seen really detailed diagrams of. You know, neighborhoods or insides of buildings. But things are so close together that you can't tell. One part from another, you know, is this a parallel line or is it a thick? Solid line or is this part of the hallway or is it part of something else? So making things. Spatially bigger. Is really important with the 3D printing. So when I printed a, let's see, me go back to the browser. Let me share again. Sorry, here. Share. Okay, Jim, why you're doing that just so you have your next question up in line. Denise is asking that they have actually a camp. They have a campus that has rounded buildings and high low floor plans. Come in one door downstairs come out another upstairs. Thanks. How difficult would it be to create a whole campus map from scratch? Yeah, well, depends how much time you have. You know, if you have a good designer and someone who knows what they're doing. They might be able to do it in a day if they're not doing anything else. If you're just starting to learn the tool. You know, it probably took me No, 8Â h. 2 learn. Tinker CAD while I was trying to make the. The brow rider finger guide. And learn the tools for getting things aligned and making the spacing just right. And all of that I probably printed out a dozen of those things before I got one that I thought was like reasonable. So, but if you got a good designer who knows what they're doing. Then, you know, it. Shouldn't take them too long. But that might be one of those things you do as an iterative process. You know, you do part of the building and then another part and another part. And, then you stick them all together. So I wanted to share this site, it's in your handouts. This is. Tactiles. That's in Europe and they have 3D models in graphics. This is consortium of like 6 countries. And all their, VI folks got together. And, have guidelines for how to print things, getting started guide. 3d models and tactile graphics. And here's, you know, some of the things. You can. There's vast quantities of stuff in here. That you can make it's a really interesting site. But what I was talking about, let me see if I can find it here. There. So this is, are you seeing this plant cell? Yes. Donna. Okay, so this was a originally, like, True inches by 2 inches. And it's just that was way, way too small. So I blew it up and made it 6 inches by 6 inches across. And made all the individual parts. Separate. And if you notice here everything in, well, let's see if I can do this. Everything in this picture. Is flat. So visually they look different. But you look at this piece here with like that looks like a bunch of teeth together and this thing with a bunch of pencil erasers in it. Those feel nearly identical to each other. And if you throw this one into the mix. Are you seeing my cursor move around? Yes. Okay, so you look at this piece and this piece and this piece and they feel nearly identical. Because they this detail in here is. Too small for your finger to discern unless you're getting in with a fingernail or something and trying to dig around and see what it is. And that's too much work for a kid to do. So what we, I think I've got these pictures here. So what I did is I added little round bumps. To the top of this thing over here. And you could feel those bumps. And the, this part I added little half cylinders to the top of. And now they're, they're distinguishable. And then the other thing I did. Was figured out. So that cell is like, so here's a plant cell 6 inches by 6 inches. And it's like, well, Kids need to know what the real scale is. Well, it turns out I did some research. And it turns out that a plant cell is One tenth of a millimeter big. Well, I can print out a one tenth of a millimeter dot and one tenth of a millimeter high. On a plate. So that's what I did is I printed out a nice plate with one little bump on it. Just so the kids could get an idea of the scale. Because our kids have a hard time figuring out what the scale of things is. So it's like, here's the plant cell with all the stuff in it that you can, you know, manipulate, explore, see what all the different parts are. And then you give them something else and says, this is how big it really is. So that they have a concept of what's. What they're really looking at. So I try and, you know, at least for small things, I try and get. Some sort of semblance and they do that on some of those diagrams. And things on. Is they use a human person as a scale so and they print out an Eiffel Tower. There's a little straight line, you know, a little line or maybe a little human. This is how big a human is is compared to this diagram of the Eiffel Tower. So you get an idea of. How big it is in in relation to the size of your, you know, average human. That's awesome. Jen, this is Donna. Debbie asks, do you have the link to the file or the cane cord twister. And if you don't have it right now, we can easily put it into the. To the file for them to download. And the I. Yes. In fact, I will, I will share it with you. I don't know that I have it online but I have the file. It's. Well. Perfect. Everybody, everything will be posted, so you'll be able to get the link to the paint. The cane cord twister. And it's sounds like people have access to 3 printers. Yeah. It does. So here in the chat is my website for those of you that are, are looking for downloads and such. I will make sure I post that chord twister with the other links. On the page. And, and the. Yep. So we will make sure we have the finger guide and the. And the cane cord twister posted on that site. And the important thing with the cane core is it makes a difference on how these things are. Printed. And it must be printed vertically. Because if you're printed sideways, it's gonna come out looking really ugly. Oh, and this one, because there's so much torque on it. When you when you twist it If you have a tough PLA. Which is a variation on PLA, which is. Stronger and It will it will last longer. And our. Oh, T also said, you know, and it's just the right size. You could use it as a signature guide if you needed. Yeah. We like multi purpose. Jim, thank you so much for coming and chatting to us about 3D printing. Sure, I hope it made. Some sort of sense. But we we got the discussion going lots of questions. Let's see. Good. And I can, if there's more of them that I didn't get to. I will be happy to. Answer them. Absolutely. Well, mark your calendars, everybody. Next week there will be no tea time no session next week. On the 20 sixth we're gonna wrap up O and M month with Audra Bishop and Kelly Nicholson they're gonna come and talk to us about how to include travel tech in your lessons. Then get ready and November. We're going to have Shannon Page come in and talk to us about Bliss Tactile symbols, another threed topic too. November ninth, Stacey is gonna come, Stacy Chambers from Kapell. It's gonna come and talk to us about how to incorporate switches into active learning. If you haven't guessed, active learning is our theme for November. Hey, King from Regent 10 is going to come and talk to us about connections and active learning, academic transition, and ECC connection or concepts. November 20 third, we will have no session for Thanksgiving and Hillary Keys will wrap off our month with active learning tech, how to make it and how to use it. Then in December we'll only have 3 sessions. Shannon is going to come back and talk vocabulary. So she'll tell us how to make the symbols. And then on December she's going to talk about how to pick which symbols are appropriate. Anita is gonna come back and need it from last month, Anita Swanson is gonna come back and talk to us about AT and music. So that's music for our Braille readers. As well as our large print, And then Stephanie Walker is going to round out our year with our APH update and I saw Stephanie in the crowd. She's somewhere around here. So she's gonna wrap up our year with our APH update.
