Here's one of the things I would change on this project. www.autoartisans.com/harmonicdrive/HarmonicDrive-10.jpg The cavity is for the same sort of 16mm bearing with either a 6mm or 6.35mm hole. Instead of 4 nuts a nut plate a 10mm hole. A rod attached to the wave generator disk slips into the bearing lining up the cup to motor. I think Sam did something similar with his belt unit.
There are probably other ways to do that too but I think that if the base of the cup is held more solidly and in line it will improve performance. I've also thought about tapering the cup so it's thicker at the bottom (say 2.0mm) and tapers to 0.9mm at the top That would tend to get rid of the hard spots where it might crack. Plus, the right way IMHO is to make the cup and internal spline out of metal.
