Hornady Comparator Tray
thingiverse
I was looking for a tray for storing my Hornady comparators (bullet and headspace) and saw something similar in a YouTube video. This one works pretty well. I was thinking about a remix that has a snap on lid. It was drawn in Fusion 360. File is attached. The comparators fit pretty tight at first. If you put them in and take them out few times, they fit well, but are easily removed.
