Bottle Cap Case

Inspired by Bottle cap crafty jig: https://www.thingiverse.com/thing:1216379

I've been slowly collecting PBR bottle caps and wanted a way to easily identify whether I had a particular cap yet. So I needed something to display the inside of the cap.

This case is sized for screw-top caps, but may also fit others if they're not too mangled from opening. It has holes in both top and bottom so you can display from either side. Since it was designed for PBR bottle caps, I sized it to hold 13, so I could print one for each suit.

Update 11/13/20: I added a stand to stack 4 cases.
