Respriator mask

THIS IS NOT A N95 MASK ! It is only intended as a temporary substitute until a proper mask can be obtained. Update 4/12/20 Changed objects scale from 10:1 to 1:1. Added 19mm elastic strap buckle. This respirator mask is based upon the "N95 Open Source Respirator Mask" by martial media dated 3/24/2020. I added a second filter and changed the nose opening. The filter is a 2-1/4" cotton round used for cosmetic care, found in most cosmetic departments including Walmart. The mask is printed flat and then heated with a hair dryer and bent into shape. The mask portion is printed with PETG filament while other parts may be printed with a filament of your choice. After printing the mask, I heated and bent it vertically along each side of the nose line to create a nearly 90° angle of the sides. Next, each side of the upper nose tabs are heated and bent downward in order to close the space between the mask and the face. Then the chin-to-face joint is heated and bent upward nearly 90°. The chin section is then heated and rounded to come up on each side to reach the panels. About 1/4" of the chin ends are heated and bent flat and upward to overlap the inside of the side panels, which are "superglued" to form a completed chin section. I have included two mask files: one with my nose profile and another blank for you to create your own fit. I also included a template file to make a custom fit. Print it out, cut it out, bend it together, and tape it in place to provide a template. Hold the template up to your face while looking in a mirror and mark the area to be removed. Then cut out the areas to be removed and repeat until you get a good fitment. Once done, use this template to customize the nose area of the printed "nonose" file. The nose seam is heated and bent so that the "V" comes together and is "superglued." This seam and the two chin points are also "hot glued" to close any openings. This design is still a work in progress and not finished yet, but I wanted to get it out there for anyone who might need one. I am temporarily using rubber bands to hold it in place, but will be changing to an elastic strap as soon as I get one. A small amount of foam weather seal tape may be used in the nose area to seal any air leakage. This design allows for wearing glasses while in use.
