Not to be used if using a common brass nozzle. There's evidence over time the brass brush will bore out the diameter of the nozzle hole.

Press in 2x M3 NYLOC nuts into the bottom of the Nozzle Brush Base.

Thread in 2x M3x16 button head screws through the Nozzle Brush Holder into the Nozzle Brush Base.

Insert the brush head into the holder.

Mount the Nozzle Brush assembly to the frame with 2x M5x10 button head screws and 2x M5 T-nuts

When the nozzle is at X min and Y max the nozzle should be a few mm behind the brush. This is to ensure during the wipe movements the X mount isn't hitting the endstop

I modified the Brass Brush Base to suit the offsets for the metal kit. You can find the files in the FYSETC Modified Printed Parts folder on my Github
