cults3d

A face mask design to help you fight airborne particles. It is a model adapted to the face of a child of about 5-8 years old. See exact size on the picture. Due to its watertightness, care must be taken to avoid the possible accumulation of CO². Being a child's product, it must be cleaned before use to remove dust residues from the printing material. You can even apply a coat of natural varnish suitable for this purpose. . Its operation requires a filtering part (cotton or gauze) and flat elastic bands. A disc with a diameter of 50 mm and a thickness of 4 mm must be made. A second set of grid 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. 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, it can be comparable to a surgeon's mask.
