Prusa XL nozzle brush wipers (M3, M4)

These can be installed on either the left or right side. Two versions are available below:

• M3
  • Left
  • Right
• M4
  • Left
  • Right

For an alternative, you can also check out my original remix, which allows you to use silicon nozzle wiper for A1 (Not mini) - https://www.printables.com/model/1316707-prusa-xl-nozzle-silicone-wiper-a1-not-mini

Print settings & orientation

• Square nuts version
  • 2 perimeters are sufficient enough I think

• Version with heatset inserts
  • Print this version on its side. This orientation is recommended primarily for faster printing and because the slot in this version does not have a chamfer.
  • I recommend 3 perimeters 

The hole for the stem is 3.5mm. Theoretically, these could also fit original stems by @Jakub Geyer, but this compatibility has not been tested.

 

All version for square nuts have also holes, where you can use flat head screwdriver to push them out if needed.

 

Brass insert version

 

Installation

Place the part approximately 85mm from the very front edge of the printer.

Tighten the bolt sufficiently to prevent the part from sliding within the 3030 profile. If the part slides due to vibrations during printing, it could move below the print sheet. Subsequent downward movement of the Z-axis could then cause serious damage.

Alternatively, and more importantly, ensure that the installed part will not collide with the print sheet at any point.

 

Screws & nuts

• 3x Square nuts
• 3x M3x12 bolts (I use DIN912)
• 1x M3/M4 T-Nuts
• 1x M3x16/M4x16 - Use DIN912
   

G-CODEs

Please be aware that I am unsure if specific G-code coordinates are universally applicable to all XL printers, as my printer is a single tool head model. You may need to verify and adjust coordinates for your specific machine.

End G-Code - could be used also for Tool Change G-Code
