Hello DDeGonge,
I like the design of your 75mm harmonic drive, and I want to use it to drive a sand feeder for my sand spreader on the back of my garden tractor.
I printed all of the .stl parts from the V2 folder, but the wave generator is not the same as the one in your video, its obviously a newer version. There appears to be a coupling of some sort that goes between the wave generator and the motor. I've looked to see if I have missed a file, but I can't find it. Is that hiding somewhere?

Thanks for all of your work,
Eufrades
