This is replacement kit for Ender 3. I hope it will help you repair and maybe customize your lovely Ender.

The only part that needs explanation is the KNOB TEST. If you want to make your custom CONTROL KNOB, you can use this part as a reference to a potenciometer axle on the printer itself (example: You hop into tinkercad, turn the knob test to a hole and put it in your conrol knob.)

No replacement parts are on the picture od my Ender above.
