When covid came, the local 3D print clubs/maker communities got together and mass-printer a variety of ear savers for the full range of local healthcare workers and first responders, then expanded to essential workers like drug store and grocery workers, mail carriers and delivery persons. [It was a variety of styles for the ear savers, because different styles worked better for different people.] It was a great effort, and we remember and remain appreciative of the help and support our community gave us.
