This version also includes files for an optional face shield. The face shield should be cut out of PETG film or Lexan sheet.

If you have your print settings dialed in, you should be able to print all pieces of this mask in about 47-65 minutes. The files for this print are also located on my website www.JoshHughes.Studio. If you're a medical official and want to collaborate in the design process, please feel free to reach out to me directly via email at Josh@JoshHughes.studio. Here's an article about using TPU with FDM in medical equipment: https://www.ncbi.nlm.nih.gov/pubmed/30961229 (if interested). The filter that attaches to the mask is a 700 series Roomba HEPA filter, though other filter materials may be used by placing the filter material over the filter cover and inserting it into the connection port. If using a flat filter substrate, ensure you adjust the x/y scale of the filter cover to the thickness of your filter material. Please note that the 700 series Roomba HEPA filter must be made from Polycarbonate (PC) and not fiberglass. The filter that fits this mask is a HEPA Filter certified to filter particulate down to .3 micron, meeting the same filtering requirements as N95, P95, and R95 masks.
