Creality CR-10 Bed Lock Knobs

These parts should alleviate the need to re-level the bed due to knob migration. Requires an M4 square nut installed on each knob. The foundation should work with springs or silicone spacers, but may require extra pressure against the corners to allow the bed screw to go thru.

Each notch of the knob is roughly equivalent to .25mm or .001" of bed height.

I bought an assorted metric square nuts kit made by Kinpar and sold on Amazon.
