Here's the 140 Tooth cup and 147 Spline for a 20:1 ratio with 0.5 module gear teeth. No backlash in fact a bit tight. ID of cup is 68.5mm so a bit smaller than the original one (82mm ID) with the big teeth and 1.25 module (36:1).
Only problem is the cup gear layer changes were all in one row and it's made more of a dip than bump and the bearings do hang up a bit on it. Funny thing too. The wave generator disk looked like crap and the bearings wouldn't fit on their posts with Cura but came out nice with Slic3r. The cup is Slic3r. The spline done with Cura. http://www.autoartisans.com/harmonicdrive/HM_Drive-140T0.5M.jpg I'm going to try and reprint the cup with random layer changes to try and get rid of the bump. Should be able to mount it into the existing box and lid and try it out.
