This is a simple hanger for pallet racking, meant to accommodate water bottles, light bags, or for use in pairs to hang brooms, scrubbers, dusters, etc.

There are 2 versions, the standard model is .45" in width to make it printable without supports, but there is a 1" version that is a bit stronger and looks a little nicer.

Printed with 5 walls for maximum speed, but note that this results in some de-lamination when heavy items are hung from the hangers. It would be better to use 2-3 walls with some heavy infill instead.

This model is specifically for pallet racking used in my workplace. This racking is exceptionally common though, but you can reference the model at the link below to compare with your racking.
