U.S. Air Force Staff Sgt. Andrew Schaeffer, 1st Maintenance Squadron F-22 Raptor egress craftsman, helped create 3D printed masks for 1st Fighter Wing personnel at Joint Base Langley-Eustis, Virginia, May 4, 2020. While the main goal was to provide masks to personnel at the 1st FW, Schaeffer also published the designs to the DoD Innovation Network, so other people can print and create their own masks as well.
