M3 Bed Leveling Knob for Anycubic i3 Mega & Others

thingiverse

I have been using MKingCharles' tire leveling knobs for my i3 Mega for years and love them. However, eventually the knobs would slip down off the factory knobs they are press-fit on. This was just enough to not look straight and level, but not affect functionality at all. I decided to remix the original to use M3 standoffs or nuts instead. There are three variations: <ul> <li>v1 for an M3 nut added during the print to completely capture it. Add a pause in your slicer before the layer that covers the nut compartment (at 7.75mm), insert nut (this may take a bit of force to snap it in, I screwed it onto a bolt to help) and then continue printing</li> <li>v2 for an M3 nut added after the print is complete</li> <li>v3 for an M3 standoff added after the print is complete</li> </ul> I currently use the standoff version with 6mm (5.94mm actual) x 13mm standoffs. I intentionally designed this to be a tight fit, so a clamp or bolt and washer may be needed to press / pull the standoff in. Longer or shorter standoffs can be used as the hex cutout goes all the way through.
