Airtight Filament delivery system (almost)

thingiverse

Air-tight food container filament holder using push-fit connectors at the top of the printer. Instructions I purchased a "Lock & Lock" handy rectangular 12-liter container with an included freshness tray on Amazon for around £17. A 200mm filament reel perfectly fits in across its short dimension, accommodating three 70mm wide reels effortlessly, while four 60mm wide reels would likely fit if needed. I printed a top plate to fit the Flashforge print head, featuring push-fit connectors for 4mm x 2mm Teflon tubing and mounting brackets to secure them onto the box's lid. Additionally, I blanked off unused push-fits to maintain an air-tight seal by keeping extra tubes sealed away. Initially, reels functioned well using my adjustable reel rollers but an alternative solution would be running them on the base of the container itself. For further safety, I stock up on bags of desiccant to keep everything dry.
