extruder filter prusa mk3s

This is my idea for a filament filter, it celans the filament, reducing the risk of jams with smaller noozles.

It has to be assembled inserting a small piece of spongy material inside the extruded cilinder (the chimney), be carefull and use something clean!

I suggest to make the hole for the filament in the sponge before mounting it, this way you eliminate the risk of pushing sponge piecs into the extruder gears.
