3D Printer Air Filter

This is my attempt to design an air filter for my 3D printer housed inside the lack enclosure. I have yet to receive the parts yet so this is still work in progress

As we know, printing certain plastics emits bad smells & VOCs. It is important to print in either a well ventilated area or have it enclosed. HEPA filters cannot filter out VOCs and bad smells and thus you would require some sort of activated carbon filter

The idea is to have the filtered air circulate within the enclosure itself for 2 reasons
- Extracting air will cause cold air to be sucked in, thus dropping the temperature and causing certain plastics to warp
- HEPA filters with activated carbon layers have effectiveness that are questionable. I'd rather have the air circulating within the enclosed space

I used the xiaomi car air purifier filter as it is pretty cheap and compact and comes with a activated carbon filter version. I added an extra container that can be filled with activated carbon which will enh
