Strong and functional clothing hanger. Model may have some imperfections but it does it's job very well. I usually print these in PETG, arms between 10-20 percent (adaptive)cubic infill. For the hook I use slightly higher infill 20-30 percent. Glue parts with a few drops of superglue on the contact points. Might require some shaving on the edges even though they have a small chamfer already. Test fit before gluing. 

It's a pretty rough model I made quickly.
