Hard Shell: Print in vase mode with a 1mm nozzle -- single wall @ 1.2 width and .4mm layer height in PETG or PLA. Face side down with no brim.

Here is an article about the use of TPU with FDM here https://www.ncbi.nlm.nih.gov/pubmed/30961229 in medical equipment(if you are insterested)

The filter which attaches to the mask is a 700 series Roomba HEPA filter, though other filter materials may be used with this design by placing the filter material over the filter cover and insterting it into the connection port. If the intent is to use a flat filter substraight, ensure you adjust the x/y scale of the filter cover to the thickness of your filter material. 

PLEASE ENSURE that the 700 series Roomba HEPA filter is made from Polycarbonate (PC) and NOT FIBERGLASS. 

The filter that fits this mask is a HEPA Filter which is certified to filter particulate down to .3 micron. This is the same filtering requirements for the N95, P95, and R95 masks
