Idle Filament Holder

thingiverse

This holder is designed specifically for your unused filament tube on a dual extrusion MakerBot Replicator 2X. Its purpose is to prevent the idle tube from being damaged or tangled during use. Although compatible with other dual extrusion models, its suitability depends on their specifications. While some may view it as an unnecessary accessory, it provides organization and protection for your filament tubes.
