I originally designed the BLUE one as I have installed the hand-screw wheel on the X plate. Then, I made the Red one for normal ender 3 pro, but its compliance may be limited by the hand-screw wheel
No additional hardware is needed to install this mod (except the brush). Compliance design enhanced the longevity of the nozzle life.
20240208: I realize some PEI sheet has handles at the corners, so I have made one more version that has a logner brush mount so you can mount the brush closer to the centerline.
this is the hotend I am using, u may need to modify the brush location for other hotend: https://www.creativity3dprinter.com/ExtruderKit_CoolingFan_MK8DirectDrive?search=direct%20drive%20ender&category_id=0
Please see the video below in action.
