Printable Snap-Lock Keyring - Strong & Lightweight

I wanted a strong, lightweight printable keyring that snaps closed, so I designed my own. This snap-lock keyring uses a barbed closure that's easy to click together, and very secure once closed. Printed in PETG, the Small size comfortably holds around 10 lbs, and the Large size holds about 25 lbs. The slip cover is purely optional - the snap fit is pretty secure by itself, but some people might want a little extra protection. Simply slide the cover around the keyring and over top of the clasp. Then no amount of twisting or wrenching can open the keyring before breaking the plastic itself. I’m happy to add more sizes or variations, just let me know what you need!Updates:2026-02-05: Added the optional slip covers.Boost MeBoosts help pay for my filament to design stuff like this!
