Montana Mask - 3 Sizes

thingiverse

This is a Modification of the original Montana Mask [ https://www.makethemasks.com/about-the-mask ] to make a better seal around the nose. The difference between each size is 1/4 of an inch. There are 3 Sizes: Large, Medium, and Small. The Large is the Original Montana Mask, unedited. The alterations are only on the nose of the Medium and Small, so the size of the cheek, chin, and flange hole is the same.
