Anycubic i3 Mega elevated bed knobs

Bed adjustment knobs for Anycubic i3 Mega, they fit over factory knobs. They are raised above the knob rim level to provide some clearance (mostly for the bed cable). It is textured with indicator arrows to help you know which way to rotate them.

The fit is extremely snug, once seated they won't come off, you'll have to destroy the well to release the factory knob. *Take care to seat it vertically!* If it's tilted it may get stuck and you'll have to destroy the knob. The easiest method I found is to pre-seat it on the factory knob while it's still on bed, then unscrew the knob, and press it against a solid surface into the printed knob. *Don't push on the rim!* Push on the butt. There will be about 2mm clearance left between the knob and the bed.

If you have dual extruder printer you can print the rim texture in an alternate color. But you can also simply paint it.
