Took an existing injection molded cubicle coat hanger and recreated it. Made a couple and they work well and are near identical to one I recreated.

I did not measure the wall of the cubicle but the inner width of the cubicle hanging section on the existing one was around 48mm/1.88" so I'm assuming the wall thickness of the cubicles this is used on is 45mm/1.75". The 3mf file is included so you may edit it to the width of your cubicle.

I only needed a couple and printed them on my Mk4 rather than my X1 Carbon so I do not have the Bambu files. You could probably hang a backpack or other items on it as well.
