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.

Inspired by face mask from ... -covid-19/

-Easy to clean design (no threads or complex parts)
-Comfortable fit (smoother, thicker contours and edges)
-Dual filters (use N95 particle sheets or round cotton pads)
-Moisture trapper (reduce moisture buildup at chin)
-Easy to breathe (Up to 300 cc of volume)
-Optional face mask seal with flexible material or TPU (print groove facing up, see print settings below)

1) Print with front of mask facing down on build plate with no supports.
Please see picture above.
2) Sand down any rough edges with 220 grit sandpaper.
3) Attach 1/4" flat elastic bands to the mask.
See picture above for an example on how to attach.
4) Press fit filter sheets using an inner ring for each vent.

1) Use a hair dryer to heat up edges and contour to your face.
2) Initial your masks in case you have more than one in the family.
