Strain Wave Gearbox - Hộp số Harmonic Drive tham số

A 25:1 ratio, module2, (almost) fully 3D printable harmonic drive gearbox. Printable with a 0.4mm nozzle

Required extra hardware:

• M3 heat set inserts

• Variety of M3 screws

• 5mm bearing balls

Important print instructions:

• Use PETG at least for the flex spline, as PLA is too rigid and will deform over time (trust me, I've been there)  -- PLA works in the other parts, bu I still recommend using PETG everywhere 

• Adding some plastic-compatible lubrication in the bearings and gear contact points will reduce noise and make it work more smoothly

(Parametric models could be made available on request)

*WARNING*: it works as-is, but currently I am still testing the parts to ensure smooth operation
