Ender 3 Knob to Dial Conversion
thingiverse
The dial features make the stock knob more user friendly and easier to turn, especially for large adjustments. I printed with 100% infill. Less is definitely going to function fine but when I used 10% infill, the bottoms of the finger hemisphere features didn't print nicely. This dial will fit snugly onto your Ender 3 knob, no hardware needed though I did add features that allow an m3 flat head screw and nut to be used if needed. It may fit other creality printers also.
