NATO RD40 40mm for secura filters adaptor
thingiverse
Easy to print, Allows use of secura bayonet filters in military and DIN masks. Main problem is thread may be starting at different angle in each mask, not only model to model but copy to copy of same model mask. This is "no problem" with round filters. Well, those aren't round and You might end up with filter sticking out in unfortunate directions. I have two solutions to that: print one piece version and shim it with gasket/teflon tape (model to be published) print two part version and glue them in proper position relative to each other You might also be interested in cheap and easy face shield design: https://wiki.hackerspace.pl/projects:covid-19:english
