Cruising through Thingiverse the other day and seen this drive.

I think I may modify this to do some testing with InMoov Shoulders.

Nice search dwilli, if you use the above drive, make sure to have less teeth to get a much faster revolution of the gear otherwise your InMoov will be very, very slow.

 

This harmonic drive was a cool one as well, but the creator hasn't gone further with i'ts developpement.

I tried printing parts when I worked on the bicep actuation, but my printer wasn't accurate enough at the time and the results were not good .
