Knob for 6mm split shaft Prusa i3 MK3

This knob fits on a 6mm split shaft. I made it for my Prusa i3 MK3; I didn't care for the dial it came with. The bottom detail is similar to the knob that came on the MK3 and provides a little give. I printed mine in natural (clear) PETG and it works great.

Modeled in OnShape, it's parametric so noodle away:
