Filament Threader
thingiverse
Similar to a cable management system, this threader is a loop designed to be mounted on a shelf or edge of a desk, ensuring smooth filament guidance. Printing with only one extruder on my Dreamer revealed that back and forth motion can create a sawing effect when the unused extruder's filament rubs against the desk shelf edge. The curved surface of this threader effectively prevents that issue from occurring.
