D20 spinner

Funky little DND dice spinner with a simple arrow indicator and pseudo-randomized numbers for rolls.
Prints in two pieces without supports, can either be used as is by sanding/greasing the inside, or converted to a ball bearing style by adding a few 1/2" (12.5mm) steel, ceramic or glass slingshot projectiles.
There is a 1/4" (~6mm) through-hole on the bottom portion in case you wish to secure it to a surface for stability.

I had originally intended this to be a print-in-place item, but couldn't quite figure out how to get everything nice and clean. Figured I should post up this since it works. I'll be updating to the new version once I figure everything else out.

I can provide the original fusion360 files on request if you want to make your own changes.
