X-Carve Z-axis spinner

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2330708.

I saw some of the other x-carve z axis spinners and I wanted to make one that spins it more freely so I made a crank type spinner. Needs a short M4 bolt and one or two washers. Bolt should self tap the hole in the knob.

EDIT: Now with Knurled knob

EDIT2: Spinner handle 3 fits more snugly on the nut.
