Face mask alternative

I did this as an alternative of the PRUSA face shield that uses less material to print. I´ve participated in a argentinian collective (Coronathon) that used that model to aid healthcare professionals. This version came out as a suggestion for the organization to reduce printing time in comparison with the design we were using.
One of my fellow collaborators had problems with the original design in his printer, so he asked me this one to try it. This one worked better for him so now i share it with all to keep it around helping where it can.
I intend this design is used only for donation, please not sell it.
Hope it suits you
