The main goal for this mod is that I can clean the nozzle after I pause and resume the print, which is usually make small leakage of nozzle.
You need 2 heat insert for the brush holder, to fixed the holder on the frame mount. Another 2 heat insert for fixing the brush like I do, for which I also drill 2 3mm holes on the brush, or you can just glue it.
Use 2 m5 screws to fixed the frame mount on the rear z extrusion, and 2 m3 for fixed brush holder on the frame mount.
Another 2 m3 for fix brush on the holder(optional).
You need to adjust the position of frame mount and the brush holder:
I upload with my nozzle scrubbing config, you may need to modify:

Make sure test before you use in the real print.
Cheers
