This is a 36:1 two stage cycloidal drive that's designed to be print in place. It is thus also limited to demonstrating the principles and functionalities of this type of cycloidal drive but cannot be integrated into an actual complex system.
Print instructions:
A quite well tuned printer is a must. specially for the half size version. Tolerances are just 0.15mm. If the parts bind together, I recommend trying some appropriate torque applied to the center axis with the help of some needle nose pliers using the cutouts in the axis made just for this purpose. If the parts still won't work, scaling up uniformly should help.
Bed adhesion is of course also key and brims thus might be necessary.
I also integrated small notches in all important PiP surfaces prone to binding to set the seams a bit back into the surface. They are designed so that the slicer should automatically place the seams in those notches but if that doesn't work I recommend using seam painting. The seams can be seen in their correct position in this screenshot as those grey dots.
