I couldn't find a pull knob that I liked so I made my own. Mounts using a 4 mm screw.

Also provided is a drill jig that will position the knob 50 mm from each edge of the door for a corner mount.

I counterbored the screw holes on the inside with an 8 mm brad point drill bit, and used the hole_plug.stl to cover it.

Update 2020-02-25: I made a version with a cavity that allows a M3 nut to be placed inside during the print process: knob_internal_nut.stl

Update 2020-02-27: Improvements to the internal nut version: slightly larger slot for the nut, and deeper hole for long screws. I also updated the hole_plug.stl to fit better and use less material.
