Creality Bed Levelling Knob - 40mm

A 40mm diameter bed levelling knob for Creality printers. Specifically this clears the Y stepper on Ender 3 printers if you've fitted heat sinks and/or stepper vibration dampers.

Recessed to accept a M4 nut. I'd suggest a Nyloc to improve bed levelling consistency, although this requires the bolt to be secured to the bed itself. A locknut works well.
