Harmonic drives, to my understanding, rely on mechanical warping to function properly, and seem very tricky to design. This relies on completely different mechanisms to work and seems far easier to design and manufacture. I would not be confident making a harmonic drive, but I could see myself making this on a 2-axis CNC, manual mill, and lathe.
