An attempt at a beveled twisted planetary gear bearing. Inspired by Emmet. Check handedness. Print 2 of the flat ones and 3 or more of the macaroons. Assembly should be pretty obvious.Looks like thingiverse has decide not to turn off "work-in-progress" automatically. I printed a working centimeter scale prototype. Two copies of topbot2 and three or more of roller2. Under heavy axial loads it does pretty well. six-18/18-six is a pair of bevel gears with a different tooth count ratio. In principle, the tooth counts of the large and small gears should be coprime to so that wear is even, but I doubt any of the builds will see enough use for it to matter.
