Prusa MK3S Minimalist Filament Cleaner

thingiverse

I didn't like the look of most filament cleaners, so I made this minimalistic version. The top plastic part of the MK3S extruder has been redesigned to allow for easy mounting of the cleaner. To assemble the cleaner, simply squish some kitchen sponge between the two hex halves and place it on the cap. Trim the sponge if necessary to ensure a snug fit. You can change filament without taking anything apart - just pull out the old one and insert a new one.
