Filament Bag Port

thingiverse

In an effort to shield my PLA from excessive humidity, I stored the rolls in a sealed bag and carved small openings for the PVC pipe that aligns with the spool center. I fed the pipe through the bag, then through the spool before it emerged on the opposite side of the bag. I also kept the desiccant within the bag to help counteract moisture. Now, how do I extract the filament from its plastic prison? Filament Bag Port! Cut a small corner off the plastic bag, then direct the filament through the cone-shaped opening that results. (This design is tailored for 1.75mm Filament; you may need to employ an exacto knife to enlarge the opening of the cone to accommodate your specific filament diameter.) Push the filament through the hole in the corner of the bag you created. Next, push the cone-shaped port down the filament towards the opening you made in the bag. Ensure that the cone protrudes from the bag's opening and then press the retaining ring onto the port, effectively sandwiching the plastic bag between two secure layers. This simple yet effective approach grants easy access to your filament while maintaining a decent moisture barrier.
