60mm Gas Mask Filter

thingiverse

This is a 60mm filter designed specifically to fit onto Serbian M1 gas masks and similar models like Finn masks. Its primary purpose is to create two layers of filtration, one made from cotton and the other from activated charcoal, which can be combined to produce a simple yet effective filtering system. Alternatively, it can be left empty and used as a prop for demonstration purposes only. Special thanks go to https://www.thingiverse.com/thing:1840408 for providing the 60mm filter threads that make this design possible.
