Updated Design for surgical filter (手術用フィルター / 외과 용 필터) in 3M Mask 3200 (Large Diameter Cartridge)

thingiverse

I learned a new software, Fusion360, to modify my previous thread design, which wasn't working out so well. Now, with this new tool, I've created a clockwork screw that's much smoother than before. To further protect the exhaust valve and prevent short circuits of stale air, I've added a cover to the new design. You can check out my previous work on Thingiverse at https://www.thingiverse.com/thing:4187215. My goal is to create a cartridge that prolongs the lifespan of surgical mask filters. These filters typically have a 70mm diameter, and I'm convinced that increasing their surface area will boost electrostatic filter efficiency. The more surface area a filter has, the slower air flows through it, allowing for better capture of viruses via electrostatic means.
