Ender 3 Control Knob

thingiverse

I was searching for a unique knob to replace the one on my Ender 3 controller. I stumbled upon an original design by vptorres0717, which was specifically made for the extruder, but it had a D-shaped opening that wouldn't fit the controller shaft. So, I decided to modify it by enlarging the opening to 6mm round, and now it fits perfectly. The modified knob doesn't have a ridged edge, but since there's minimal torque involved in controlling the Ender 3, it stays securely in place and functions flawlessly as intended.
