Semi-Planetary Ring Gear Reverser Widget by mikexnxike

Last crawled date: 4 years, 1 month ago

This is just a cool spur gear contraption I made for fun. It is basically a planetary gear set without the sun gear. The two outer ring gears rotate opposite one another if you hold the casing stationary. I computed and designed the gears from scratch, took me a few tries to get the ring gear diameters right so that it didn't seize, so it should work without any modification. The two housing components are press fit together, and for me it was quite a bit of a press fit, though it should work. I feel like this can vary from printer to printer though. If you print one post how it fits together and what you think! :)
