M4 Replacement Bed Leveling Knob

This was designed to house a 5.3mm M4 nut to replace the wing nuts provided with an Anet A8. It's a tight fit, so accurate calibration is required to get a snug fit, and may take some persuasion to get it seated nicely.

Obviously due to the heat, appropriate filament would be recommended for this part as it's going on the hot bed!
