Split ring compound planetary gear [1:120 ratio]

[For nema17 steppers, ratio : 1:120] Hi,This model is inspired by this video by David Hartkop. It is a reductor designed for a NEMA17 stepper motor with a high reduction ratio.I'm currently printing this with my new P1P, but I already printed a modified version with my elegoo MARS and it worked well. The current ratio is 120, but thanks to David's spreadsheet, it is easy to modify this value. I designed it with onshape as a parametric model, here is the link. Let me know if you face a problem, and have fun with your printers
