(Functional) RESPIRATOR GAS MASK V2

Improved Heavier duty version of my gas mask/Respirator design, Now its half the size, easier to print, Looks great, Less than half the weight and has two options for the Purge Valves (One way valve). The problem with the old design is the valve has to face up otherwise it does not work, The Improved valve works even UP SIDE DOWN, But requires more parts. The filters are made like the older filters just make sure you are using Activated Carbon for gas filters and not fluid filters.
