So you want to make a cube? First, draw a square. Then, draw another square slightly offset from that one. Then connect the lines. You now have you very own cube!
Ok, just kidding. What I'm actually going to do is cover the basics of what I did to make my very own game-accurate Plushie Companion Cube. So maybe you can make your own!1
If you would like to skip to the end, and are interested in just buying a pattern from me rather than attempting your own, please contact me at nekonariko at g mail.2 Subject: "Companion Cube Pattern". I need to see how much interest there is before I decide finalize the production method. Cost is projected to be $25+shipping. Some assembly required.3 You are paying for the time that I put into making this pattern. And the paper. And the ink. But my time and skills are the most valuable parts. The actual cube and data are owned by Valve. And if they have a problem with me selling this, then I will cease to sell, as long as they promise to read my open letter to them. And implement my suggestions.
But I'm not selling anything you can't do yourself. So basically if you buy it, it's like cheating, but in an awesome way where I get to buy more fabric. In full disclosure, it will be helpful if you know a bit of basic trigonometry, and maybe even some 3d modeling knowledge. Or you might get lost. And I'm going to show you how to do this, but I'm not going to do it all for you. Unless you pay me, at which point, you should just buy the pattern. My rates for on-site tutorials are insane.4
This tutorial will be in two parts. The first part will cover how to make a pattern. The second part will be tips on constructing the actual cube. I'm going to alter my techniques a bit, because I have learned a lot since I made my cube in 2008/2009, and I think that you might benefit from that experience. I know I do.
So if you want to learn how to make a pattern, go here.
If you have a pattern, and you want some tips on cube construction, go here.
