Ender 3 V2 Nozzle scrubber

Nozzle brush mount has adjustable Z height for glass or PEI beds. Uses custom klipper macro to scrub after extruder hits temp and just before purge. Requires two 3mm x 4mm heat inserts, and two 3mm x 6mm screws. Mounts using right front bed leveling knob.

Use PETG if possible, pla may work, but will droop if temp gets high
