A simple mask which provides protection against coronavirus or other viruses. You must buy a filter to place in the mask. You should buy elastic to hold it on your head. The scale can be modified according to the size of the user's head. This is the second mask I've designed. Update: Added a stl which is the part attached to the head that takes up the least amount of material. Update 2: An stl has been added which is the same mask but with some external fittings so that there is no possibility of outside air entering from the holes in the original model.
