I created this system because I didn’t like using advanced filtration while printing safer materials like PETG and PLA.
How does it work?
When you use the advanced filtration fans, the flaps are closed by negative pressure and gravity.
When you switch to the built-in fans, the flaps lift up and let the airflow bypass the filter, extending its lifespan.
How to print and what do i need?
Material: PETG or something better.
Screws: 4x M3x4rT + additional 4x M3 from spare parts.
I recommend printing the flaps and the case separately. However, I also uploaded a full 3MF file with everything together if you want to save some time.
Print flaps with 0.15mm or 0.1mm profile.
Use Automatic supports organic. Just select to No generate supports here.
Assembly:
Then screw screws mounting adapter to advanced filtration and holding "ears". Everything should holdup together then you can mount flaps and mount whole thing onto to printer.
*I am uploading step files if someone will make some adjustments. Folder "StepFiles".
