Creality Control Knob With Knurl

Replaced the control knob on my box with this guy. It doesn't improve the scrolling on the screen since its roughly the same diameter as the oem knob. However it feels a lot more comfortable to turn due to the tapered geometry I designed.

The knurl feeling is very mild. If you prefer a more aggressive feel, try sanding the knurl surface lightly to roughen up the texture.
