Fidget Three with Planetary Gear Center

Designed to remove the need for the difficult to print ball bearings, this uses a planetary gear center instead.

Although the original fidget spinner was suggested to print at half scale, the teeth of this might be difficult to print out correctly at that scale. If you print any smaller, then you might not have enough clearance between the teeth of the gear. I've tested this on Repetier-Host and got pretty good resolution printing it at 1:1 scale. I'm also using mm as my unit base instead of inches, but that shouldn't do anything.

I've tried to match the design of the original Fidget Three as closely as possible. As with the original print, it comes out a bit big. I printed mine at 0.75 scale, but it will probably also come out okay at 0.5 scale.
