Ender 2 Pro QR mounted nozzle wiper

I wanted a nozzle wiper for my Ender 2 Pro, just like BambuLab printers use to clean their nozzles before printing. So I measured the distances and made this nozzle wiper to fit a cut piece of A1 silicone wiper (which you can buy from Temu or Aliexpress very cheap). Or you can use something else which matches the height.

The wiper-arm just snaps on the hanging part of the QR-cap (it's a very tight fit and difficult to snap) and the whole thing snaps on to the cover which originally has the QR sticker.

Easy to print:
 - Any layer height could work, it just depends on how you'd like the parts to look. Mine are printed on 0.2mm height.
 - I suggest 3 or more perimeters (outer wall) for the wiper arm, or higher infill percentage (more than 30%)
 - Any material even PLA would work for the QR-cap, but I suggest PETG or ABS for the wiper-arm, cause it's a bit close to the nozzle.

You would have to make and add your own gCode in the start gcode in the slicer, or if you use Klipper it's even better to put it in a your config file. This is my Klipper code that just moves the nozzle to 0.2mm height, then moves the nozzle 5 times through the wiper and brings it back between the wiper and bed.

This gcode uses absolute coordinates, make sure to add it after the the printer finishes it's homing procedure (edit: made it go faster and a bit further to properly clean the nozzle).

gcode:
    G1 Z0.0 X-3.0 Y2.0 F1500
    G1 X-19 F5000
    G1 X-10 F5000

    G1 X-3.0 Y2.0 F1500
    G1 Z0.28 F1500

I put this right after the bed and nozzle reach temperature and before the purge line.

Let me know if you need help adjusting the model or the gCode.
