There are currently 2 hooks in this collection. The first one is basically @Andrews hook with a less curved nose, so my level slides easier on it. The other one is a stronger version I designed to hold my cloth hangers.
It's a fast and easy print and and should work without any support. Print in the orientation specified. I'd recommend to print in PETG for stability and to avoid material creep, as you would encounter with PLA (but feel free to try).
I included the source file, in case you want to improve on this or adjust anything.
As it is designed with a non commercial license of Fusion360, I can't allow commercial use, sorry for that.
The author remixed this model.
