This is an easy-to-make face mask based on a model widely used in the early stages of the COVID-19 pandemic. This model is still widely used by dentists and hospitals. The features of this model include increased thickness of the arm, as this part was prone to damage in the original model, and longer support for the protective film to provide better stability for the entire face mask assembly. The protective film support at the bottom ensures the shape and stability of the assembled product.
The protective film must be accurately punched or laser-cut according to the attached diagram.
