Healthcare workers on the frontlines of fighting COVID-19 are turning to an unlikely source for help with the shortage of personal protective equipment (PPE)—librarians. Madiha Choksi, along with her colleagues at Columbia University Libraries, developed a guide for rapidly producing face shields with 3D printers. Choksi modified a mask design for production speed and will collaborate with Tangible Creative, a 3D-printing services company, to make more shields to meet growing demand.
