Follow the success of vacuum the 1st Zip Bag Nozzle design (Ziploc Bag Vacuum Adaptor by 3D-Dreamer - MakerWorld), I've asked by friends to model an adapter which can fit onto a regular vacuum cleaner.

Background: I'm living in a place where indoor humidity is around RH 60% - 75%. I don't have a filament dryer. Instead, I keep the filament spools in Ziploc bags individually with desiccant silica gel packs. I used an electric air pump to act as a vacuum to suck out excessive air in the bag so that the desiccant packs can work easier to keep filament dry longer. Typical air pump or vacuum cleaner do not comes with flat profile adaptor suitable for sucking out air from a ziploc bag. Thus I designed a very slim profile adaptor with holes along the tip and edges for effective suck out of air from filament Ziploc bag. Ziploc bags can slide out of the adaptor after vacuuming for quick sealing without letting air goes back into the bag. Hope you will find this adapter and the original one useful to keep your filaments in dry condition longer.

Please print this using 0.2 mm nozzle to ensure the tiny holes are formed nicely.

If you have  an camping air bed pump, you can use this model instead: Ziploc Bag Vacuum Adaptor by 3D-Dreamer - MakerWorld
