Replicator 2X Filament Dust Filter

thingiverse

The Makerbot Replicator 2X's filament rolls can accumulate dust, potentially clogging nozzles. To prevent this, a specific filament dust filter has been designed for the Replicator 2X, not occupying extruder space. Its removable filters can be cleaned without unloading filament and are securely designed to avoid accidental dislodgement. The tube support assembly clips together and fits into Rep2X supports, with a render available at http://youtu.be/t04y_zX4_pE&autoplay=1. All parts can be printed without supports, and warping-prone parts have tear-off flanges to minimize the possibility. For the filter blocks, use a 2cm cube sponge that is elastic when dry; slit it down the middle about 80% of the way through for easy filament insertion and locking.
