Backpack Hanger

This is a small hanger for backpacks or other bags. The rod in my closet is the thin 8mm type so I didn't want a large hanger designed for 30/35mm rods, which seems to be the majority of models. This hanger is designed with a 21mm inner diameter so should work for up to 20mm rods.

Because it's a flat design, it should also be stronger than angled designs — but I didn't do stress testing to see how strong it actually is. The model is 8mm thick and with a good infill (I used gyroid at 30%) I find it quite rigid.

Update 2025/09/01: Added a larger model with a 28mm inner diameter for rods around 1 inch. Useful for hanging caps to dry after washing.
