Ender 3 Super Knob

thingiverse

This is a revised design built upon tmhanks' original concept. I've incorporated numerical values for fine-tuning positioning and directional arrows integrated into the side of the knob. The 6-32 hardware variant features a distinct nut size accommodating a 6-32, 9mm nut. This specific hardware can be obtained at Lowes Hardware Store under item number 490413, which includes 10 screws and 10 nuts. The extra nuts can be utilized as jam nuts to secure the screws against the bed, ensuring that the knob adjustments remain precise. The nut holes within the knobs are carefully crafted to fit snugly, requiring the nuts to be pressed in place. If you're fortunate enough to possess a small hydraulic press, this task is relatively straightforward; however, an alternative approach involves using a small C-clamp. To protect the protruding splines, a small socket can be employed with ease.
