About this model

This is a mechanical part for coupling a typical stepper motor with a 5mm shaft to another shaft of 8mm. Initially designed for 3D printer, but could be used for many applications. Print with a high extrusion multiplier, 1 or maybe 1.03 to be sure of strong interlayer adhesion. I used 3 perimeter, and 25% infill.
