The main difference between an ordinary painter's
breathing mask and a N95 medical grade mask is the
plastic exhale valve. 

Are there 3D printer plastic adepts on this list who
want to measure an authentic 3M medical mask valve
and generate a 3D printer program to make a duplicate?
We might need many of those masks for coronavirus during
the next few months.  Extra bonus points for turning
soda bottle plastic into 3D printer feedstock.
