This is a remix of the cool Hyperbolic Planetary Gearset by jsteuben. I modified the tri-joint and connecting-rods so that no screws are needed; the entire thing now just snaps together. I also made the central "24 90" gear slightly narrower to enable the gears to spin smoothly. And I added a handle to the "small hex key" to make playing with the gears more fun :) Just a note: this is not actually a "planetary" gearset, although I kept the original title. It is a cool gear assembly, prints well, looks amazing, and it's fun to play with, but in an actual planetary gear there's an outer gear which rotates around the inner gears. Printed using standard settings on Makerbot Rep 2, with rafts. The gears, connecting rods, and hex key will print best vertically. Print: To assemble the gearset:
