Okay, maybe you will have some idea. I try to attach this (3D printed) mini to some kind of temporary base for painting instead of the one that she came with as it would be otherwise hard to paint both. However, when I tried to make holes on plastic bottle cap, they won't hold her in place and trying to drill 0.8mm for wire didn't work either. It also seems so delicate that I'm seriously afraid of doing anything rough with it. Any ideas how to hold her in place?
