When repainting one of our rooms we managed to misplace one of the curtain rod hangers shown below.
Luckily I was able to design up a replacement hanger using the FreeCAD software!
It’s not quite a 1:1 replica as I needed to add a support to make sure that it wouldn’t break under the weight of the curtain rod. I was also unable to perfectly capture the shape of the holder but I think it works well enough!
Ignore the misshapenness of screw holes as I had a hard time taking the supports off of the print! If you’re interested/have also misplaced a similar coat hanger the file to print this is available on Thingiverse.
