Golden Hills 4-H club volunteer project leader, Jemetha Cosgrove, and her two children, aged 12 and 7, repurposed their 3D printing equipment – part of a 4-H AgTech project – to make face shields to help in the COVID-19 pandemic. As of April 13, they've made around 120 and are donating them to medical and other essential workers in the North Bay.
They are using a Prusa MK3 printer. Prusa popularized the home face shield 3D printing movement from its headquarters in Europe and it has continued to spread around the world. Their shield design and others are being widely used by health care workers during the pandemic. The Cosgroves have been printing a design approved for use in hospitals by the U.S. National Institute of Health.
Each print takes about 2.5 hours and can take longer or shorter depending on the shield design. They are also printing bias tape makers, used to make mask ties, to support the cloth mask sewing efforts. They invite others who own 3D printers to join the effort.
