Ender 3 Control Knob

Was looking for a different knob for the Ender 3 controller. Found the original by vptorres0717, but it was for the extruder and had a D-shaped opening. I just opened it up to a 6mm round opening, and it fits on the shaft for the controller. It doesn't have a ridged opening, but since there's not a lot of torque on this control, it sits just fine and operates the controller as desired.
