Mod(hack) Covid 19 mask

This is my remix of COVID-19 Emergency mask by Navakasi https://www.thingiverse.com/thing:4267890 and remix Covid Mask with exhale filter by BigLatte https://www.thingiverse.com/thing:4307198.

I also borrow some parts from Modified Montana Mask by Masterkookus Thingiverse: https://www.thingiverse.com/thing:4251440

Background:

I liked the design but the nose section was too narrow. I widen that area, so I could put in the weatherstripping liner. Also I did not want to deal with the screw threads. I told Masterkookus concept and made all the holes circular smooth for hex insert. Best to use 1 3/16" o-rings for all the intakes and exhaust. Of course the exhaust has the same dimensions, so could use it as a third filter. I removed his strap attachments. Instead I put in trianglar loops. This allowed for no supports and bigger holes to easily attach straps. Made an adapter, for the filters. But would probably change the filter attachment to fit hex insert. Also added some some mate
