Nozzle cleaning brush holder

cults3d

Nozzle cleaning support for ender 3, ender 3 pro and ender 3 v2 compatible brushes. You need to cut the brass brush flush, and secure it with an M3 screw. The whole thing is stuck together with double-sided tape. The nozzle must rub at the height of the conical part, not lower, and the Z must remain constant. I enclose the part of my personal Gcode to adapt to your machines before printing. Ideally, the machine does its home and then its levelling (for those who do it every print) then the nozzle is moved during heating to the starting point of the off-bed cleaning in order to have the off-platen oozing.
