3D Printed Ring type strain wave gear test

I made a ring type wave gear made with a 3D printer.


There are various types of wave gears, but I tried a ring type prototype. The flexspline was made using TPU filament, the ball was made using 8mm BB bullets, and the others were made using PLA filament.
