Montana Mask Simplified

This is a remix of the Montana Mask updated for single piece simplicity and much increased airflow.

I take no credit for the original design (see below).

Please support the original work.

This remix enables the use of filters made from sources such as HEPA vacuum cleaner bags, and features a large filter area to increase airflow. The filter is attached to the mask using a simple elastic band.

For bonus fun, the filter is large enough to draw some optional facial features!
