OpenSCAD Tips and Tricks

OpenSCAD Tips and Tricks
Triangles Right triangles in the OpenSCAD documentation they say how to make a triangle. They use an array of points and then you can use another array to make each and every face on the object. Now I see that this can be helpful on some things! But this is a terrible example, because a triangle is simple to make

module triangle(){
        rotate([0,0,45]) cube([50,50,50]);

This will make a triangle with a 90 degree angle!

Equilateral Triangle If you want to make a equilateral triangle you use a cylinder, this is kind of a weird thing to think of. But we are using a cylinder with a specified number of sides, this can be extremely useful in a number of ways. But we can use it this time to make a triangle.
cylinder(r=5, h=5, $fn=3);
That $fn=3 is the magic! This tells the program that it is only allowed to use 3 sides to make a cylinder, and the best it can do it a equilateral triangle. Define the number of si…

3D printer enclosure

IDEA I was talking to someone at youmagine and they said that it would be cool if their was a propper enclosure for their printer, this would help with the safety of kids with a printer in their class rooms, this is a very good point. Printers are very hot and dangerous kid! It would also help out with thing like warping parts and all of that. people make these things out of cardboard all the time. HOW I DID IT I wanted to do a little bit more that cardboard for these guys. So as the norm I took to OpenScad to make up the parts needed for this thing, and I did something a little different that what you normally see me do, I made 2D drawing. In cad you can do things like cube(); normally but most people don't know that you can do things like square(); and make 2D things, this is what needed for something like a laser cutter. So I made up some corners, and hinges and a handle for the door. Those parts you have to print, and then with a very settings you can also render out the file…

I was featured on youmagine

IDEA I want to make a video that explained how I do most of my stuff with OpenScad, and I thought a video would be the best way to do just that.
EXECUTION I, my self do have stretched ears, and I have wanted to make some plugs for a while now, so I did just that! This video is How I make most things in OpenScad, and in the end I show how cool it is to use fontawesome with your projects. If you havent seen my other video on how to get fontawesome working in OpenScad go and check out my other video that is linked in the description of this one.
After I posted this model up on they messaged me and said that they were going to feature my model :) This made me feel special, so I am very happy with it. I also got talking to them and made another projects with their help, its a enclosure for your printer, to keep your printer safe in a class room situation, and keep the heat in, This should help eliminate any warping issues that you are getting with ABS. But that will be anoth…

Magnetic Finger Implant

Intro This is not my first magnetic find implant, my first one is a super tiny one in my left middle finger, right in the center, I can only really feel strong magnets with it, So I ordered a new magnet from Dangerous things. I got a m31 and had the idea of implanting it with a needle, (this went bad and the magnet was not implanted) I waited for a few months without putting it in. It was actually stuck to my dads fridge for a long time in a plastic bag. Then I finally had the time to do it, so I asked Rick Lee if he would help me out and do the cut, since I just cant get my self to cut my own finger. He is a super nice guy and agreed, and didn't even complain when I was dripping blood all over him.

I would say that the experience was not to bad, I would say around a 3 on the pain scale, I had my finger in some ice before hand, and I think the adrenalin kept me feeling alright. We cut it open, slid the magnet in by hand, and used another magnet to pull the magnet to the extent of…

Customizable 3D printed Quad copter

The Idea I wanted to make a 3D printed quadcopter, because I wanted to to do quad racings, but I did not want to just put a kit have loose out on the fun of making something cool for my self, and I wanted something that can change in any way I want  it to, if I want six inch props then I can have them, but what if I wanted something weird? like maybe I found 7.4inch props some place and wanted to optimize my quad to use those. So you have to have a design that can change, and my design can in fact change to whatever size you want. The Making I used openscad so that I could set parameters for the prop size, and some others tuff, and I wanted to make the frame have slots in it for velcro/zip tie downs. So I have a few holes in the frame that you can define how you want it to work, now I also wanted to be able to use a large battery, and their is not room for it on the top of the frame, so I decided that the battery should go on the bottom. I also wanted to race this thing. So I have som…

Resin for FFF printers

THE IDEA So a lot of people that want a 3D printer always get lost in the mix of FDM (same as FFF), and SLA. Now SLA is nice because it uses a freaking laser (on the head of freaking sharks) to cure the resin in a pool and do so very very accurately, and a FFF printer lays how plastic, this is much faster but has less accurate prints, and if you want to print clear things, its not so awesome. So the idea was to make an thing that would make your FF printer print with resin, just to see how it goes! and I mean why not right? resin is liquid and we use water tube fittings for the bowden tube, so it should be pretty well water tight, and if not, you can just blast the leaking with some UV light to close the leak. But this is a weird thing, how do you properly get resin to come out of the tip of your hot-end in a nice flow? I though you would use something like a Z axis on a standard FFF printer and clap down on a bag pushing the right amount out of the tip.

THE MAKINGJust like I do, I m…

UPDATES on the Benbot now known as the dollo 3D printer

NEWS In news, we were published on! It was a huge deal for us. They found our project from github, and that is kind of weird since github is where we has our code, and nothing really about the printer, and we never sent a link to anyone about it, I am thinking that they just scrape github for anything new that comes up that mentions 3D printing, But still way cool! Also My mini factory (mmf) Contacted up and said that they really like the idea too, so we at some point are going to be doing some collaboration work with them, I am not sure what the will be yet, but it seamed pretty cool. I have never had so many people interested in something that I have done before, so it it really exciting. I also entered the 3d print contest on instructables, but did not make it into the finals, I think this is do to lack of me promoting it. But the good thing is that it forced me to make full documentation on how to assemble the Dollo 3D so now anyone who want to can go and make some wi…

Parametric VR headset

THE IDEASo this idea came about not to long after my last blog post quite some time ago, the things it, I was not quite versed enough in Openscad to finish it up and make it something that I was happy enough with to share, But now I am a lot better with openscad and I now have finished a parametric VR headset in openscad, this means that you can open up the file and change how the headset works, you can specify how large your phone is, and what size of lenses you have, and with what I have done, your computer will make your a custom headset! You can also specify a few extra things, like if you want a headset, and what kind of head strap you already have laying around, this way you will be able to reuse old part, maybe from an old VR headset that you dont really like any more, and you can do the same thing with a magnet slider on the side, so that it will work with all of the google cardboard apps.
So really the idea is a VR headset for everyone.
WHAT YOU DO WITH IT This headset is me…
