Borgomanero, Italy - April 2020 - In this time of medical emergency, the students of Prima Les (address of the Social Economic High School) of the "Don Bosco" College of Borgomanero, thanks to 3D printing, and coordinated by the teacher Assia Hassanein, have created elastic devices for safety masks. The intuition is the result of the inspiration and creativity of Quinn Callander, a 13-year-old Canadian boy, who made his idea available without a patent and free online, allowing the students to thus implement the project and customize it before printing. The device lightens the weight of the mask elastics and prevents rubbing on the back of the ears, avoiding irritation and injury. So far, 100 straps have been supplied to the Obstetrics Department of the Borgomanero Hospital and another 100 to the Vergante Ambulance.
