Ender 3 Super Knob

This is a reMix of tmhanks original design. I've added numbers for adjustment positioning and directional arrows inset into the side of the knob.

The 6-32 Hardware variation has a different nut size to accept a 6-32 9mm nut. This hardware can be purchased at a Lowes Hardware Store, item number 490413, which comes with 10 screws and 10 nuts. The extra nuts can be used as jam nuts to tighten the screws to the bed so that the screws can't turn, giving the knob adjustments more accuracy.

The nut holes in the knobs are snug and the nuts will need to be pressed into the knobs. You can do this with a small hydraulic press if your fortunate enough to have one, but alternately you can just use a small c-clamp. A small socket can be used to protect the protruding splines.
