#DISCLAIMER WARNING! USE AT YOUR OWN RISK. THIS IS NOT A SUBSTITUTE FOR A PROPER COMMERCIAL CARTRIDGE FILTER. THE DESIGN IS ONLY A FILTER HOUSING. YOU MUST SUPPLY YOUR OWN FILTER AND MEDIA. I AM NOT RESPONSIBLE FOR YOUR USE OR MISUSE OF THIS DESIGN. CONSULT A MEDICAL AND/OR OCCUPATIONAL HEALTH/SAFETY PROFESSIONAL FOR GUIDANCE.

###Background This is a result of me wanting to create both a housing that could use standard 5N11 style filter media and a DIY organic vapor filter cartridge. The result is a modular system that can be built into either:

• a particulate only filter, akin to using 3M 603, 501, and 5N11
• an organic vapor/gas filter like a 3M 6001
• an organic vapor/gas/particulate filter like a 3M 6001 plus 5N11 and 501 retainer

###Description This housing fits the standard bayonet fitting on 3M masks and requires you to use your own filter material/media. See post-printing section for assembly instructions.

###File Explanations

• main_housing.stl - main component, similar to the 3M 603.
• Connector_3M.stl - 3M bayonet attachment (glue to main housing)
• side_wall.stl - outer wall of the housing that provides volume to contain filter media
• top_cover.stl - cover that fits over the side wall to contain the filter media
• top_cover_infil_modifer.stl - modifier mesh to tell your slicer to print no top/bottom layer so that air can flow into the filter

###What filter should I use? WIP

###WIP/TODO

• MSA bayonet connector
