Just a simple clip to attach a Casio F91W to a molle loop or any other strap it fits on. I suggest printing it with PETG or ASA since it'll just snap if printed out of PLA. Kind of a pain to print due to low bed adhesion.
It's strong enough to lift my backpack from the watch, I haven't carried out any longterm testing tho.
