given the scarcity and shortage of the masks due to the CORONAVIRUS
EMERGENCY, I took some time to create this mask, to protect us and our... loved ones or at least a little !! ,
THIS MASK IS ;washable and sanitizable with interchangeable filter .
AND _ it is quite versatile, just enlarge the stl model to your face type.
you will find two models, one more suitable for a round face and another more suitable for an oval face
****The author does not claim that this mask is a known virus panacea, but I think it is better than the paper ones, and its protection depends very much on the filter you use.
I hope it will help
