This is a hook for hangers, with ridges that provide spacing between them.
I really liked paulblamire's hook design (https://makerworld.com/en/models/117988), this remix is a quick trim down to make it a little less robust since it's going to be holding clothes rather than a ladder, and I added the hanger ridges. It's still overbuilt for the task but looks nice and won't be going anywhere.
The print in the images is Duramic PLA marble.
