This is a makeshift brush mount for the Ender 3 V2. It requires 2 m3 bolts to attach the brush.

It requires a drill to put mounting holes in the brush head. And a third m3 bolt to attach the mount to the printer.

This also requires a firmware that allows the commend G1 X 245, standard firmware only allows G1 X220. Th Jyers firmware is what I am using.
