Awesome - i knew we had some 3d modeing experts here. So what else is needed to turn this into a functional gearbox? 2 gearmotors, 2 shafts, some screws, and (4?) bearings?

Can shafts be lifted from 3:1 gearboxes? Where to get gearboxes? Possibility for some kind of worm drive instead of planetary gearmotors?
