This is a model of a folding hanger I designed to hang my smelly shirts at the gym's locker-room.
It consists of 2 parts - 1 hook and 2 arms which are connected by 3 shoulder screws (5mm shoulder diameter, 10mm shoulder length).
I Designed it for aluminum laser cutting, but you could easily print it in ABS or similar polymers.

shown in one of the pictures is an IKEA elastic cord used in the SKADIS pegboard system that I re-used as an additional clothesline to hang a towel.

It is somewhat crude - but it's compact, strong, lightweight, and looks RAW AF - GUARANTEED to make you the weiredest bruh in your gym. 😉
