PRUSA I3 MK3S fs-cover upgrade -- Filament Cleaner


Filament cleaning modification of the open-source file "fs-cover" in the collection of 3D Printed parts used in the assembly of the PRUSA I3 MK3S 3D Printer. The workshop my printer is currently in can get fairly dusty, and it was affecting my prints so I designed and printed this, put a small piece of firm kitchen sponge in the cylinder and I douse it with a bit of mineral spirits before and during every print. Haven't had any trouble with dust since. Note: I used PETG for heat resistance, and it was a bit stringy leading to some issues with initial threading of the two pieces, but I just screwed and unscrewed it for about 5 minutes to clear the threads, after that it worked fine.
