Pin Badge Display
thingiverse
As much as I love pin badges, the backs come off way too easily when I'm wearing them, and I don't want to buy barrel locks. So I slapped a few shapes together in Tinkercad, and made this display board. Mine warped a little (should have printed a raft, I fancy), but it still does the job.
