Prusa CORE One Nozzle Wiper

This is a Nozzle Wiper for the CORE One that uses a A1 style silicone brush.

You will need a knock off Bambu Lab A1 wiper brush. I got mine from Ali Express. 6 for €1.20. Just make sure they come with adhesive tape at the bottom.

You will also need a single m3x5.7 heatset insert. I used the ones from cnc kitchen.

At the moment I printed this in Prusament PETG and it holds up just fine so far, but I will reprint it soonish with the new HT-PLA from Polymaker.

Update 1 - 17.08.2025: I reprinted it in PCCF now, but there was really no need for that. The PETG version held up perfectly fine even when printing PCCF for several hours. 

Update 2 -28.08.2025: I added 2 new Versions. One that uses an M3 Nut instead of a Heatset Insert and another Version that allows you to just screw a M3x10 Scre directly into the part. I do reccomend the Heatset Insert Version still though. 

Anyway, if you want to use it, you need to add the following lines into your printers Start G-Code in the Prusa Slicer right before the original nozzle cleaning gcode. I personaly put the new cleaning method before AND after the offical nozzle cleaning, just to be absolutely sure the nozzle is clean. 

WARNING: USE AT OWN RISK!  The supplied ocde works for me but carefully check if the coordinates work on you printer too, before this slamms your printhead into something.
