Pinholder for Painting and Airbrush

This solid block with lots of holes lets you stick in skewers/pins with the parts you want to paint on them. The holes are arranged with increasing angles toward the outside so that the parts on the skewers don't touch each other.

I printed the block from PETG, so it weights about 300 g. To increase the weight further, I filled it with Raysin plaster, bringing it to 1.8 kg. Three rubber buffers can be glued to the underside for a secure footing.
