Any verification if it works well or not? Looks like a lot of printing so I figured that I would ask first. Looks great!

Wow! Nice Work, How much torque can it handle?

Very nice, Are all the part printer in PLA or ABS? also what's the reduction

Sorry for not mentioning that. Everything is printed in PLA ( from ICE FILAMENTS), except for "Gummischeibe", it is printed in TPU but can be PLA too if TPU doesnt work with your printer.
The reduction rate is 55:1.

Thank you, Can you share the how to calculation the reduction

nF / (nC - nF) = rotations:1
nF = number of teeth of the Flexspline
nC = number of teeth of the Circularspline

in my case:
110 / (112 - 110) = 55:1
