This is a remix of a cubicle coat hook from bharris555 with changes to fit my work cubicle walls. The walls have fabric with a metal top. I printed it solid in PLA + and it will hold a full backpack with no problem. You can use less infill and walls if you are just hanging a lightweight coat.

I remixed it by: adjusting the size up to the width of the cubicle wall top (69.82 mm), cut out the shape of the top so the hook sits flush when on, I made it a little taller so it wraps around the wall more, added more material to the front and back of hook so it will press against the fabric wall more, and cut off material at the same angle on the back and front to be able to rotate the hook over the wall without bending it much.

Print settings I used on Elegoo Centauri Carbon
.4 nozzle
.2 mm layer height
100% infill
No supports needed
