In late March, a number of Harker families began making face shields to help local hospitals deal with a projected surge of COVID-19 patients. Having heard that 3D-printed face shields had become popular, Harker parent Mary Yang (Andrew Pangborn, grade 4) reached out to her friend, Jian Chen (Kevin, grade 5, and Julie, grade 4), who owns a 3D printer, and asked if he could produce some masks for her and her co-workers at Kaiser Permanente in Santa Clara. The family of Emma Lee, grade 5, and Anna Lee, grade 8, also joined the effort, and the group ended up printing and assembling 100 masks. “The doctors and nurses at Kaiser loved them,” reported Yang.
