Added a buckle STL file for use on elastic straps, as well as a snap-on splatter guard cover. Splash guards STL files have been updated for both male and female standard width masks. 2020-04-08 A comment from a medical professional friend regarding the use and fit testing of these masks: "I had the 'male-narrow' mask fit test done on me today, along with a new N95 model I hadn't used before. Both masks were tested using the 3M Qualitative Fit Test Apparatus FT-30 (bitter). We started with the 3D printed mask and it passed the fit test. My filter setup includes a precisely cut rectangle of Filtrete 1900 material flush on the inside front of the filter box, followed by eight to ten pleats of the same material, and finally an oversized rectangle on the back of the filter which protrudes from all sides when snapped onto the mask. Although it's not the most comfortable option, it seems to work well. For straps, I cut down a rubber exercise resistance band into approximately 1 cm widths and adjusted them so the mask fits very tightly to my face. This setup does not validate the filter or mask officially."
