Stoneham single extruder filament cleaner

Cura allows base and cover to be assembled prior to printing. This was done in the G code file, so it prints all at once. After removing all supports and raft, carefully flex hinge to break it loose. The interior is filled with 2 small pieces of foam that put mild pressure on the filament to wipe it clean just prior to entering the extruder. When the foam wears, just rotate it 90 degrees or flip the faces front to back to get new cleaning surfaces.
