Face mask to protect against air born viruses like coronavirus. Mask is not a one-size-fits-all. You may need to print at different scales to see which one works best.

Features:
-Comfortable fit for extended use
-Optimized strap buckle design for 3D printing
-Dual filter (use N95 particle sheets or round cotton pads)
-Moisture trapper to prevent moisture at the chin

Disclaimer: This is not a replacement for proper N95 masks. If you can get your hands on N95 masks, please do so and use those. If you cannot, then having this is better than none.

Please comment on your fitment and any issues you had. Thank you.
