Was asked to make a reproduction of a plastic shim that, oh I’ll get this wrong, sits between red dot and mount on a Glock 99. The difference is, the new one was to be wedge shaped, around 4 degree taper. I had a go, black Delrin, and it worked. Little rough around the edges, I need to find a way to gently de-rag small plastic parts. Maybe a vibratory tumbler.
Anyway, just sitting back and waiting for the rush of new orders 🙂
