This is a re-maked version of the air filter design by Armus on Thingiverse (https://www.thingiverse.com/thing:6397034). If you like my design, go to his project and give it a like.s
UPDATE:
I've included a new version of the plate with a wider gasket for slightly larger holes. I've also added a grip edge for easier screwing and an optional cover without external threads for those who don't want to use a cap or will be putting the monotube in direct fruiting conditions. The print file includes the optional cover.
Supports not needed.![]()

The insert has a diameter of 37mm, matching one of the various standard measures for hole saws, making it easy to adapt for various hole dimensions resizing or editing using a slicer or 3D modeling software. (A Fusion 360 (.f3d) file is included for easy modifications.)
The original design uses a twist lock, In this full remix i redesigned the box attachment and the lid and I have added threads to ensure airtight, preventing loosening or falling off parts.
The design allows for easy insertion or replacement of polyfill or filter material without removing the entire assembly. Simply unscrew the outer part, replace the polyfill or filter, and screw it back on. It also features a screw-on lid to block airflow for increase CO2 levels in your grow setup when needed.
