grabcad

This design addresses the shortage of masks for Coronavirus protection. This design is made up of three elements: 3D Printed Cartridge: There are two threaded parts, with an internal piece that's sewn onto the external fabric. Fabric: Two pieces of identical size must be sewn around its perimeter to leave a pocket between them. The outer fabric needs a hole to sew on the external cartridge. Polipropylene paper or fabric: It will serve as the filtering agent against the Coronavirus and hence will be disposable, placed in the pocket between the fabrics.
