Parametric Shaft coupler with hex support
thingiverse
This is a small enhancement to marcsulf's excellent parametric Z coupler. Our robotics team needed a more general coupler that could support hex shafts and also be non-flexible. 1/26/2014 - Attached is the STL file for a version that prints on it's side. After testing we found that printing that way was stronger. The insides of the hex would tend to strip before the part delaminated. Do Not print with PLA - Too brittle If printing with ABS print with 4-5 shells and high (50%) rectilinear infill. Then finish either painting with Acetone or in an acetone vapor bath. Best bet is printing with Taulman 618 Nylon.
