Updated Design for surgical filter (手術用フィルター / 외과 용 필터) in 3M Mask 6200 / 7502 (Large Diameter Cartridge)

I upgrade my software skills by learning Fusion360, allowing me to revamp the thread design. This new design yields a smoother, clockwise screw thread. You can view my previous design on https://www.thingiverse.com/thing:4181495. My goal is to create a cartridge that extends the lifespan of surgical mask filters. The diameter of these filters is approximately 70mm. Increasing the surface area (to 70mm) of the surgical filter improves electrostatic filter efficiency. A greater surface area results in a lower air flow rate, leading to increased effectiveness at capturing viruses through electrostatic means.
