Adattatore - COVID-19

thingiverse

Here is the rewritten text: To use the snorkeling mask as a respirator, you need an adapter. The adapter lets you use circular filters of various diameters designed to filter the air breathed by the user, protecting the respiratory tract and face from external agents. You can view the adapter designed for 80mm diameter filters in the attachments; it's possible to design one that allows mounting filters of different sizes with a conical connection and pressure locking. The object is not flexible and non-toxic because it was made from a plastic material derived from the transformation of sugars found in corn, beets, sugarcane, and other natural and renewable materials and not derived from petroleum (unlike traditional plastic).
