I wanted to spruce up my bookcase doors with some nicer doorknobs, so I whipped up two different versions in Fusion.

Screws in easily and grabs the scew well.

I would recomend to print these with atleast 4 walls, so make sure the inside walls are sturdy enough for the screw to bite into,

Printed at 0.1mm with 25% infill.
