Protective mask COVID-19

cults3d

I've just created a COVID-19 mask; full nose and mouth protection. Washable with alcohol or products such as soap. The goal is that it will be reusable at will unattractive, but you are protected. We need to help our caregivers, so let's print them out for them. It is designed to be able to integrate a cotton round with a 3 um fabric. Before screwing. The aim is to save the number of filter changes with regular cleaning. I created it for this purpose. It avoids projections or contact of the hands on the mouth. A little I like where a thank you will please. !!! Don't hesitate to put a picture of the mask, to see your realizations. Thank you.!!!!
