Chastity Key Holder

thingiverse

This is a case for standard keys for holy trainer style locks. It can hold up to 2 keys at once and is designed to work with common electronic time lock padlocks. Just insert one or two keys, put the lock loop through the holes in the case + keys and lock it up! (Hole diameter: 5mm, total length: 51mm) Edit: I realized that the previous design was just about fragile enough to break apart with fingers, so I've added another model that's 50% thicker and should be very hard to break into without tools
