Airtight Filament Container - PTFE Tube Fitting

thingiverse

This is a precise fit for the Rubbermaid 21-Cup airtight storage container that enables 1.75 mm 3D printer filament to pass through into PTFE tubing without being exposed to air. It demands an M12 hole to be drilled into the container, and the nut and bolt components screw together through the hole to seal against the container securely. The exterior half of this setup also includes three caps that can be used to seal the other end of the PTFE tube when not in use.
