Montana Mask 90% scale (Small) with normal sized filter opening

thingiverse

This is a smaller version of the Montana Mask. Initially, I simply scaled down the whole thing, but then decided to give it a normal size for the filter suitable for smaller faces. This smaller mask uses the same filter holder as the original mask. The original mask can be found here: https://www.makethemasks.com/. I'm also including the filter holder here as well. https://youtu.be/h_MmtO9nQec A video on how to assemble and cut out filters from HEPA. Cut the weatherstripping to about 12.5" for this smaller mask.
