stand alone ender 3 v3 ke run out sensor holder to mount the sensor to the gantry if the spool holder has been relocated. easy print ,no supports, I printed mine with 2 walls and 15 percent infill you will need to replace the original m3 screw and spacer attaching the arm to the holder with a m4 12 and a lock washer and unclip the unclip the cable at the end and run it under the gantry.
The author remixed this model.
