cults3d
A face mask design to help you fight airborne particles. It provides partial containment of your airway. Its operation requires a filtering part (cotton or gauze) and flat elastic bands. A disc with a diameter of 65 mm and a thickness of 4 mm must be made. A second set of screens is supplied for a filtration thickness of 14 mm. The "cartridge" is then closed and the air is filtered. then simply adjust the elastics to his waist. A test profile is provided to allow the best possible adjustment of the print scale. You can also warm the mask slightly (50-60° C) so that it fits the shape of your face perfectly (use a cloth to protect yourself). This model is designed to be manufactured without support but you can use it to have an optimal quality of the elastic fixing rings. warning this device is not FFP2 level.
