TPU airtight mask with screw in filter compartment. HEPA or what ever you can find. I used F8 Fiter material. Size is on the small side but can be scaled up and is tolerant. Optional face shield included as DXF or within the STEP File. Print the Mask and intake form antibacterial FIlament if you can. TPU-Seal.stl from TPU the softer the better or make a mold and use silicone. Use "inclusive" slicing toilerance in cura to make the thread work better.
