About this 3D model

Protective mask with large intake to lower the air pressure and increase effectivity of the filter. I recomand to use nonwoven nanofiber, but even using cotton cloth should help you to protect others and yourself against the Covid-19 virus. The low profile filter holder (objimka nizka) usually works better.Print on fine layer settings (0.15mm) to get smoother surface that are easier to clean.For dissinfection use 70% ethanol or Isopropyl alcohol bath an let it there for at least 3 minutes. The mask was developed in colaboration with Czech Technical University in Prague. The mask builds on original design by lafactoria3d
