Glue-on nose piece for KN95 and other masks

cults3d

The cheap KN95 masks I got on ebay have nosepieces that don't keep their shape very well, and need constant adjustment. So I made myself a plastic nosepiece I can glue on the mask with Shoe Goo. It took five prototypes to get one with good fit for me, so it almost surely won't fit you, but maybe you can tweak the parameters in the Bezier curve defining it. I also made one for my son by having him press a wire around the bridge of his nose and then scanning the wire and fitting Beziers to it in Inkscape (that's the shorter and wider variant). Since I'm reusing the KN95 masks on a weekly basis (the inventor of N95 masks recommends airing for seven days as the simplest way to disinfect), I don't mind that it's permanent. My files are likely pretty useless to you except as inspiration.
