Mask Concept

thingiverse

A mask concept for TPU, printable in rigid form for added comfort. Combine multiple rubber bands in a loop to achieve a snug fit. If printed, please provide feedback on how it fits, as this can lead to a more universal design. Those skilled with CAD software can immerse themselves and use the waterline to create a custom fit, using an object of known size next to their face for scale. I'm not an expert in materials science, but this design allows for easy layering of various filter materials without sewing.
