M3 Bed Leveling Knob
thingiverse
This upgrade thumbscrew knob fits any 3D printer bed using an M3 screw / nut for leveling purposes, making it a versatile solution. The M3 nut securely fastens into the bottom of the knob, ensuring a snug fit that surpasses metal wing nuts on some printers. With its diameter of 35mm and height of 6mm, this knob provides ample clearance, eliminating potential issues with particular printers. Two variations are available: one without cutouts and another with cutouts (v2). When installing the knob, it's essential to place it first with the M3 nut cutout facing downwards, allowing the knob to sit on top of the nut and secure in place.
