Sinusoidal Planetary Gear Set

This is a pretty large set of planetary gears. There really isn't a purpose for these, I just thought it would be a fun CAD exercise. I didn't use a gear generator like the one found in Fusion, but rather modeled the gears myself the hard way as the CAD program I used does not have a gear generator. I hadn't seen a gear with teeth that follow a sine curve so I wanted to give it a try. 

The gears are Module 2, N 52 on the ring, N 16 on the planets and N20 on the sun gear. At full size there is 0.2mm of backlash designed in. If you scale the model down to print just remember that this value will decrease so make sure your printer is capable of tighter tolerances.

I printed these in PLA with a 0.2mm layer height.
