A fully mechanical solution for hands-free management of the Core ONE Vents that work via air pressure from the rear exhaust fans.

To install, simply use a spare length of filament or similar gauge steel wire to hold the flaps to the vent body.

The Fusion360 project file is included to show the process of creating this from scratch. Remixes and mods are appreciated.

Happy printing!
