3D printed face mask designed for easy filter replacement and complete disassembly for cleaning. The modular design allows for user to quickly change the attachment method (elastic straps, rubber bands, elastic tubing, etc.) by swapping the single MOD Ring component. This design allows for use with whatever supplies are available and has a large mouth opening for breathability with different filter materials. Only one MOD Ring is available now for use with elastic strap materials.

Please see Instructions for Use for assembly informations and other required components.

Additional MOD Ring designs will be uploaded here but feel free to design your own as you see fit (.sldprt file is uploaded, additional 3D file types are available at request).
