# FaceCoveringChallenge Masks are in short supply, and time is of the essence. This design can be printed in under an hour without requiring any assembly of 3D printer parts. I created this mask from a modified version of another model found on this platform. Print it with the flat side facing down. This file is intended for adult use only. Scaling Options: 110% scale yields an Adult XL size 100% scale yields an Adult L size 90% scale yields a Medium/Teen/Female size 85% scale yields a Youth/Child size You'll need the following materials: 3M 1500 or 2200 series bacterial/viral allergen air filters 1/4" or 1cm elastic straps Foam adhesive weather strips for windows to add near the nose for an anti-fog seal Rubber bands or hair ties Now it's your turn. You can also use boiling water or a heat gun to soften the mask after printing for a better fit.
