I wanted to use an RCelectricparts 3530-8 1400 brushless motor, but needed to shorten the spline and adjust the motor bracket. I transferred to Freecad, and modified. Freecad files attached.
I kept the 2-part spline as the original, but don't print them in place if your printer isnt calibrated perfectly. just place them side by side.
Printed with .15mm layer height, 100% infill, no supports, Prusament ASA
The author remixed this model.
