About this 3D model
A Novelty Desktop Toy. A basic single planetary gear with a piston attached. The ratio is 1:2 allowing for a point on the gear tooth to travel the length of the shell diameter in a linear motion. I've connected a shaft piston to this point using a cut length of paper clip. It probably could be redesigned better. But works fine at the moment :) Enjoy I gave my Printed version away, and didn't take any pics. Ill post some next time I print it again. 5/06/2013 Vertices fixed ! Also Shortened the crankshaft so that it does not protrude as much. Updated files Files housing.stl and PlanetaryGearAndPiston-ALL-Parts.stl
