pic: Finally Done!

I like the gearbox-- it looks like some nice work. I'll add my voice to the people that would recommend against printing this for actual use on a robot-- I think the others have done a pretty good job of explaining why that's a bad idea. I can say firmly from experience that it isn't nearly as good an idea as it first seems.

That being said, printing certainly has its place in the design of an all-metal gearbox if you want it to. Last year I had a decent amount of success doing a high shell count and drilling/reaming essential holes, and it's always nice to test the geometry in practice as well. With a little bit of adjustment and a small amount of work, you could probably do a manually powered version to print and test before you made a metal version. I'm not entirely sure how beneficial that would be, but it would certainly be cool/interesting to show off.
