Face Mask with Cotton Pad Filter REMIX

thingiverse

This is a remix of the original junaling face mask found on Thingiverse at https://www.thingiverse.com/thing:4228729. The original mask was too small and too shallow for me, so I modified it to fit over my chin, which should be more comfortable, along with changing the strap mounts. I used a makeup cotton pad as the filter (57mm) and it fits perfectly. To make a thin filter medium seal properly, use a washer. The snap-on reverse air flow is from https://www.thingiverse.com/thing:4265806. The gasket mold can be found at https://www.thingiverse.com/thing:4256265. You could potentially make a virus killer filter with salt using the information found on ResearchGate at https://www.researchgate.net/figure/Mask-with-salt-coated-filter-for-prevention-and-deactivation-of-airborne-pathogens-a_fig1_312081831. I'm not a scientist, but I think this might be helpful when you change your filter medium. However, it's unclear if the filter has enough surface area to dry properly. Make sure to sanitize it properly with alcohol. Unfortunately, I was unable to open my files, so I didn't create versions with a hole for one-way valves. If I can manage to get them open, I'll make them and upload them. Sorry about that. There are three sizes available: small_mask, dual_gen2_sealClear, and mask_gen2rev5. The small_mask is smaller by 6% in the Y and X axis, using the same filter mesh as the other versions. I created some new filter mesh versions and made changes to the locking mechanism clearance since some people told me it gets loose over time. The origClear version has an original clearance of 0.4mm, while noClear has no clearance at all (0-0). I also rounded most edges. There are two different versions: one for cloth filters (vacuum bag, etc.) and another for makeup pads.
