Awesome you took the CAD plunge. Alibre was at the top of my list too.


Id wager your printer is culprit. Some are better than others. Should be able to tune scaling in each direction. I've never totally solved it. Bearing pockets need a pretty tight fit. The slight compression of each layer squeezes it a bit wider.

3D printing is certainly a bit more involved than push button, receive part.

Is it possible to assemble the axle halves, and thru drill/ream the bearing pockets? Or are the end opening too small?
