After installing the Creality Direct Drive Extruder upgrade kit on my Ender 3 Pro, I was sad to see that the tool plate/carriage was more narrow than the stock part and didn't engage the x-axis limit switch at it's min position. I didn't want to attach anything to the delicate limit switch, and I couldn't find a limit switch bracket that extended the needed distance (13mm); so I created this simple bumper model! It's sad to loose bed space, but the upgrade has been nice. I've included the FreeCad model file in case you'd like to fit it to your needs.
Note
The bumper is 20 mm wide, but when installed correctly it ‘extends’ the reach and reduces 13 mm of x-axis bed space.
