I designed this storage clip for my Thule Omnistor awning opener so I can store it behind the backrest in my Hero Camper. Some models seem to come with those clips factory installed but mine didn't. So I designed my own.

I printed them in PETG with four outer walls for stability. As orientation on the print bed I choose to put them sideways. In this way, the layers are orthogonal to the direction of pull of the clips.
