The Spline cutter worked great

Cutting the splines on the extruder stepper motor was very easy with the spline cutter pictures. below.





The first set of 11 0.7mm splines were cut with a  4mm spacer in place on the dremel spline cutter with 36 steps between each spline the spacer was then removed and another 11 cuts were made making the splines 4mm longer.
