Ender M4 Bed Leveling Knob (for double nut)
thingiverse
This is a knob that I'm using to double-nut my bed levelling on my Creality Ender 3. It uses an M4 nut to press into the slot, which is everything needed. If the nut does not fully press in, use horizontal expansion in your preferred slicer to shrink the knob slightly so the nut is press fit.
