We worked closely with our local hospital to successfully test these designs. Table of Contents Section -- Contents 1 ------------ Licensing Information 2 ------------ Summary of Mask Variations 3 ------------ Zip File Contents Necessary Files for Each Variation 4 ------------ Filter Material Link 5 ------------ Materials/Tools Needed With proper post-print assembly and materials, this mask design can pass a fit test. **Section 1.

Summary of Mask Variation** There are three variations available: * Press Fit * 2T * 1T 'T' stands for 'Thread'. The only difference between 2T and 1T is that 2T has two threads, making it easier to start threading and providing a more even seal. 1T is included in this post so replacement parts are available for those currently using it. 2T and 1T both use the same materials: * MaskDisk (soldered and hot glued to mask orifice) * CapDisk (Used to separate filter materials - only if multiple filters used) **Section 3. Zip File Contents Necessary Files for Each Variation** The zip files contain the necessary files for each variation: * Press Fit: + Mask + Filter + Elastic * 2T: + Mask + Filter + MaskDisk (soldered and hot glued to mask orifice) + CapDisk (Used to separate filter materials - only if multiple filters used) * 1T: + Mask + Filter + MaskDisk (soldered and hot glued to mask orifice) + CapDisk (Used to separate filter materials - only if multiple filters used) **Section 4. Filter Material Link** For filter material, use this New York Times article for reference: https://www.nytimes.com/article/coronavirus-homemade-mask-material-DIY-face-mask-ppe.html#click=https://t.co/6I9AwrbvxI The article mentions that air filters with MERV rating higher than 12 or Microparticle Performance Rating (MPR) of 1900 are suitable for use in these masks. We have been cutting 70mm diameter circles to place inside the mask. **Section 5. Materials/Tools Needed** Materials needed for all mask variations: * Some form of elastic to hold the mask on the face. * Closed-cell foam to seal the mask to the face (Weatherstripping) * Hot Glue/Hot glue gun to connect foam to contour of mask For 2T and 1T: * Soldering Iron. This is used to solder the MaskDisk to the Mask. **References** In the design of this mask, the facial contour from the Montana Mask found here: https://www.makethemasks.com/3d-printing was used.
