Really Quick Robot Wrist

Does exactly what I say in that video. There is a lot of room for improvement but I did this whole thing in like 2 hours so I'm pretty pleased. I never even made gears in CAD before this so it was a nice surprise. I'm so pleased in fact I got the stupid idea to try and make a 6 axis robot arm by stacking 3 of these together. Of course they'd have to be different sizes and all. But still, the idea is cool and it should be fun. Maybe I will do it, maybe I will do something easier that still uses this like a robotic turret or something, I'm not sure.
