This is a canister with a twist lock lid and a loop for a carabineer to hang it with. Designed specifically around harness work, rock climbing, route setting in a gym, bolting outside, or really anywhere you need storage that can be hooked up somewhere. There's four versions of this: The basic version, the routesetter version that has storage for the two standard allen wrenches used, plus 3 inch and 6 inch versions of both.

The lid turns about an eighth of a turn to latch into place. It has a mark on one side where the lid should fit onto the canister, then a turn latches it from there. There is a loop built into the lid and a place on the carabiner loop where you can tie a paracord to keep the lid captive while you're working in a harness.

Print time is something ridiculous because I've included all of the versions, but the short one is about 4hrs and the tall one is closer to 9hrs. I recommend PETG if the canister is going to be used outside. I've included the .blend versions, with the model in basic format pre-smoothing so users can adjust the canister to specific lengths if so desired.

Only hardware needed is 4x m3 socket cap screws, maybe 10mm long for the base.
