I hope You'll find it helpfull.
It is a simple respiratory mask valve to apply in any kind of respiratory/protection masks. It allows usage of less breathable fabircs for the main part of the mask which can help to increase the protecion.
it is designed for 60mm in diameter, regular cotton pads or any other medium, that can provide any protection (eg. coffe fillters).
Parts snap in place.
You'll need a 40mm hole in the fabric, preferably reinforced by fusing interling. Bottom part secures the valve to the mask.
Feel free to use/modify files in any way.
