Adult Face Mask / Respirator

This is a modification of the design by lafactoria3D. The new design provides a better fit, simplified printing, and improved airflow.  Print with PLA, with 40% infill, no supports needed. Use a handheld hair dryer to mold edges to face if needed.  USE CDC RECOMMENDED FILTER MATERIAL.  It is the user's responsibility to ensure a proper fit and use the appropriate filter material (see chart and guidance document).
