Okay, so have you ever been on your browsing through Thingiverse or favorite 3d printer file site? And you come across something. Yeah, these are great. These buttons look awesome. You go to download it and you see a file that says. SK today, this video. I want to teach you how you can use those. They are extremely powerful, but definitely a little bit more complex to use than just your simple. STL file. But if you want to unlock the power of customizable features that other programmers work very hard to put in their code. This is what you want to use so. I’m gonna get started by just explaining the typical STL work file. You go to think of ers’t you get your. STL note that it’s not customizable. It’s just a few. There’s a hole in there. You don’t like tough. Look, deal with it unless you want to open it and edit in some other program. Forget about it, so you slice up this thing with slicer? Kirra makerware, or maybe simplify 3d If you have a lot of money and you’re gonna print it, so that’s typically how you do it. See when you do it with an S CAD file things a little bit more complex, but with that complexity comes an immense amount of power to get exactly what you want. So this is what we do. You go, They’re similar, so I’ve highlighted the different steps. Yeah, you’re gonna go get your file from wherever you’re gonna go and open. You’re gonna open your s. CAD file, you change variables and this is where the power. This is the whole step that makes this a powerful is that you can change the variables. I’ll show you what I mean in a second. Then you’re going to compile and render it into an STL. That we’re familiar if we already know how to do that, and then slice with Slicer and Kyra make a rare or again simplified 3d Now you’re gonna printed, okay, so there’s a few more steps you can see, you know, we’re adding a couple steps to this process. Okay, first of all, you’re gonna need to go to open s CAD because this, you need to get this software, so go to open S CAD Dot Org and press enter. You’re going to go down to other OSS to make sure we get the correct version or two downloads and you’re going to go down. You can get the Mac OS version right up here, okay, so Windows stick to these two. The exe s. You’re either going to get 32-bit or 64-bit. If you don’t know what type of operating system you have, you can always check by typing in system and you can see. I have 64-bit operating system. Okay, so I would get the 64-bit version. Once that’s done downloading, you’re gonna double. Click it and install it. I’m gonna fast-forward through that stuff. It’s already haven’t done and you don’t want to watch my hideously disgusting Internet and slow download speeds, so I already have that installed, so go back here. Let’s grab that S CAD file or whatever s CAD file. You want to play around with I want to do. This is for a friend that wants to make buttons for her creations. You know, she sews things and makes all kinds of cool stuff. So she wants to make her own buttons. That are customizable any size any shape within the reason and you can make them any color you want to with depending on the filament you choose, so we grab the s. CAD file and wherever that downloaded to mines right here. Just gonna click that and open it up okay now. This pops open now. I need to really explain something carefully to you. This is very important. This is how s. CAD is massively different. You see this window over here in most 3d design programs? Almost all of your work is done in the visual window. Yeah, you got other menus around and some text dialogs that you could customize things, but all mostly on 99% of time. You’re working in this window, whereas in open s. Cad this program. All this window is is to show you stuff. Yeah, it’s interactive in the sense that you can rotate the camera view, you can zoom in and out. There’s other things too, but basically, you don’t do any interactive design work in this window. This is just simply a rendering. It’s just after you’re done all the after you’ve done and you compile it, You can see what it looks like over here. You cannot change anything about the S CAD file from here. You can just look at it. That’s it, okay, so if you want to change stuff. What’s interesting is is. If you look see, for example, here, you can see the programs drawing a cylinder. This is this is code. And when we compile all this set of code, it makes this button. Its exact precise instructions on how to make that button. And what’s cool is you don’t have to use numbers for the whole size. You don’t have to put in a number, it’s parametric, so you can put in a variable so instead of the thickness being a number in this code down here, it is now simply well thickness that we define up here as three millimeters. So what’s cool, lets? Check this up, sit with us. And in this file, weirdly enough, this means diameter so you can see in the programmer’s notice. This is a good programmer. They give us a hint that we should go between 14 and 72 a lot of massive buttons, giant monstrosity of a button 60 millimeters that’s over, that’s! Well over, you know, two inches. Okay, so we’re going to go to thickness. You can see the thickness. Oh, and wait a minute. Thickness is four. Now notice what? I’m changing this. Nothing’s happening over here. This the same stupid button. We started with right, okay, so what you have to do? Every time you change something, and by the way, these semicolons are really necessary. Leave them there! Just change the number part. You just double-click the number don’t! Just grab that part. You know, let’s just change that, so watch. What happens to see the changes we’ve made You have to press the f5 key at the very top and all those keep those. F keys at the top of your keyboard that people seldom use press those f5 refreshes. Hey, there’s my giant one and you can see. It’s gotten a bit thicker lip type. You know what? I like the pipe lip, check this up. Personalize and press f5 and look what it did. It put like a pipe curved lip around on the edge of it and the lips eyes on it like. I said this is a giant freaking button. And it says the zero to five Someone actually make that as big as I can’t five. You can try bigger. I don’t know, but this is. The programmer made that number. So if I want stick to. What they’re suggesting is? The hole count is a big button. We’re gonna need four bowls. I think nothing I know anything about sewing. It all terrible. The holes should be spread out pretty far because we need lost support for a giant button like this. I’m gonna go to the maximum of eight millimeters flatness. This is interesting! They put notes over here. If you want it to be concave, put a negative one. That’s what it is now. If you want to be flat, put a zero, see? These are the little hints to you from the programmer. The guy who wrote this code here in this case. So it’s one is convex so long ago. One and okay, so this giant monstrosity of a button. That’s what I want, I don’t know. Maybe this is for some big jacket or something. Whatever so there it is now you can press f5 Now here’s the deal you need to press f6 at 5 just for preview so you can get an idea of what you’re doing, f6 When you’re ready to export it to an STL file because recall we still have to in this process, we still need to compile it and render an STL and then do this. We still have to do the same thing. Just you generate your own. STL, based on what you want with these variables and usually the variables are at the top of the page. So I’m gonna go SGO. It says nothing to render press f6 so press f6 this takes a little bit longer, especially with those curved surfaces that I added to that lip. That’s going to take a little bit. Curved surfaces are not truly curved and real life. They’re polygons and it takes thousands and thousands of polygons to simulate a curved pipe surface like that. Alright, so there there it is, and now we can click up here. You click export. Ssto and I’m going to just go ahead and do that to the desktop. I’m gonna call it big button. Okay, now from here. The process is just like anything else any other. STL file that you downloaded from someone else. Except you compiled this one yourself from this very talented. Two programmers Toad, right, okay, here we go and here’s my file that the big button slide it on there. And now you can print it in your favorite software or whatever. Hey, if you like this video, go ahead and give it a like, share it. If you think it’ll feel like somebody that you know that the sewing is a makerspace and could also be 3d printing, and you know what? Hey, if you don’t like this video, something wrong with it, give it a dislike and do you, but just do me a favor and comment on how I can improve my videos, thanks.
