This is a simple heightened narrow bottle cap holder, that is designed for miniature priming before painting (or spray varnishing after miniature is painted).
I screw a bunch of those on a narrow wood scrap so I can easily spray several miniatures easily, after sticky tacking the miniatures to regular soda bottle caps.
I can then re-screw the bottle caps to a drying rack as well as my 3d printed painting handle.
No supports are needed for this to print well, I used 4x30mm screws.
