Restroom or port-a-john keyring
thingiverse
We had the need at work for a keyring for the port-a-john key on the jobsite. People have been taking the miniature padlock and key home by accident. This is a remix of https://www.thingiverse.com/thing:2004803 to turn it into a keyring. I did a color change at 2.60mm.
