#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 ###Updates 2020-10-04 - Initial Release
