I needed a model of the IKEA Bjärnum Hooks I have in my flat and so I quickly made this in Fusion360.
The hooks aren't sold anymore, so maybe this could be useful for people who need more of them or who just like the look.

Mounting holes are currently 6mm (1/8 inch), but if you want to use slimmer screws, I would recommend adjusting the size before printing to prevent having too much of a gap.

Added .stl, .3mf and .f3d files so you can easily print and edit them.
