Anycubic I3 Mega S Nozzle Wiper

The holder sits flush with the heatbed (I installed a 5mm aluminum bed) so that the silicone piece sits directly above the bed (but not too high to clashwith the print head while printing).

You need to extend your Y-axis to 224 (be sure to not update it in the slicer as it will then print in the air). 

If you don't want the pince with the heat inserts, print the one from the original model.

Install it in the back left corner (see pictures). The macro (use at your own risk, I am no expert when it comes to Klipper macros) moves the nozzle between 25 and 100 (x direction) at ~1.2 z height (though this depends on how tight your bed screws are).

If requested I could also add a version that should fit the stock aluminum bed (+ glass), though I don't have the original bed anymore, so I cannot test it. 

Parts

• Silicone Wiper
• 2 Ruthex M3 heat inserts
• 2x screws M3

Print instructions

I printed it at .28mm layer height with a 0.4mm nozzle and in PETG (though as it touches the heatbed ABS would probably be the better choice - I put a piece of kapton tape on it, to shield it a bit from the heat). I did add tree supports on the top of the silicone cutout.

The original model uses a wire brush, I wanted to use a silicone wiper (like the BambuLab A1). The pince uses M3 heat inserts.
