Creality Control Knob With Knurl

thingiverse

I replaced the control knob on my box with this custom version. Unfortunately, it doesn't enhance scrolling performance because its diameter is nearly identical to that of the original knob. But turning feels significantly more comfortable thanks to the tapered design I came up with. The knurl texture is very subtle. If you prefer a more pronounced feel, try lightly sanding the knurl surface to roughen up the texture.
