Ender 3 Bed Leveling Knob
thingiverse
The Ender 3 Pro has a clearance issue with its stepper motor dampers installed. When these dampers are in place, the stock back left bed leveling knob encounters the motor before the limit switch is triggered, causing a problem. This new bed leveling knob provides extra clearance, allowing the Y axis to move freely without obstruction. It's recommended that after replacing this knob, you adjust the Y axis limit switch forward slightly if the bed support still collides with the motor.
