Hi! This little gearbox was created as a means to get more rotation out of a standard 90 Deg 9Gram servo. I left it running back an forth for an entire 16 Hours and it still works remarkably well. I printed mine out of ASA at .2mm layer heights, but you can feel free to experiment and let me know how that goes.
You can change the drive points, spin the outer ring instead, there's TONS of ways to use a planetary gearbox, so have fun with it and feel free to modify this design into whatever you might need!
Cheers,
