Covid mask remix with exhalation valve by Bastrym

Last crawled date: 4 years, 2 months ago
Remixed mask (https://www.thingiverse.com/thing:4225667) with the exhalation valve and possibility to use another filter.
Membrane is made from inflatable ballon and glued on the raised part in the middle of the valve part.
The possibility of using a thinner filter thanks to the frame filter holder.
Supports only for valve part.
!!!!!!BUT who has a printed original mask without valve can add this valve!!!!! https://www.thingiverse.com/thing:4239168 It is much comfy and works better because the
membrane is bigger.
