Moldovita Hill – VOLTPOT®
3D printed Covid-19 reusable face mask.
Printing time for all components was about 11 hours.
If you have a 3D printer, you could give it a try. It fits well on a male’s face, but you should resize it in your software if plan to use it for kids or women. ( https://www.thingiverse.com/make:784954 )
