Tiny Planet

I created this small mechanical sculpture using almost entirely 3D printed parts. The axles are steel, and there is some metal hardware as well: shaft collars to hold the axles/gears in place, a couple bronze flanged bearings and some ball bearings to make the central axle and planetary gear parts move smoothly. I decided not to 3D print the entire machine because I wanted the axles to be small (1/8" diameter), and 3D printed parts rubbing against each other produce a lot of friction, and I wanted this machine to move smoothly with minimal force.
