SpongeBox SquarePad

thingiverse

Create a 15x15x15 cube sponge enclosure for cleaning filaments prior to entering the extruder. This device also acts as a bug barrier, preventing insect invasions that can lead to contamination inside your Mk4 printer. To use it, print and insert the provided 15x15x15mm sponge into the box, then guide the filament through a 10mm slot on the side of the sponge. Finally, attach the SquarePad* onto your Mk4 for a cleaner printing experience.
