Mark
Face mask strap for mounting a face mask instead of wrapping the mask band around the ear. This relieves pressure from the wearer.
For one face mask, 2 of these parts need to be printed. After the parts are printed, the slots and nubs are aligned and tape is used to keep part from separating. The reason for two parts is to be able to tightly pack in many parts into a build volume.
