I have found several hooks, but no one fulfilled my needs, so I have made one loosely based on similar hooks. Now you can print a car tire-sized hook!

I use them for scooter and bike helmets right at the main door entrance.

in the scad attached you can tweak various parameters of the hook. If the wall-part is longer than 30mm there are two screw-holes. Print them with 0.4-0.5 fill, 2-3 perimeters with full speed.
