Fired by Corona Masks/Respirators

thingiverse

These masks were designed by a team operating out of North Georgia. Use at your own risk. These masks have not been certified by NIOSH or the FDA, and their effectiveness and safety remain untested. Respirators and masks can cause respiratory distress due to carbon dioxide buildup, posing serious risks including death. People with pre-existing medical conditions such as pregnancy, chronic respiratory issues, or other health concerns should avoid using these masks altogether. Thousands of these masks will soon be in use by major regional healthcare systems. To achieve maximum impermeability when printing with an FDM printer and a .4 mm nozzle, ensure that at least 4 shells/walls are used.
