Painting handle

This is my take on a miniature painting handle. I designed it with a knurled surface for better grip and for the awesome look!
I'm using magnets for the top to stay on to the handle and allows the top to rotate.
The magnets I've used are 20mm in diameter and 3mm thick so the slots are for that size.

UPDATE:

I've added a support to rest the hand on. This requires Top2 aswell. I used 20% infill on both parts for the support.
