42mm thick cubicle wall hook
Add infill based on strength needed for what items you plan to hang from it. I started with a 10% infill and tested with a 15 pound back pack but may want to go more infill for long term use. I typically hang hats and coats from this hook.
The author remixed this model.
This is for thinner walls, also made the hook side longer, with a longer back as well to reduce the hook moving as much when hanging items from it.
