MSA to 3M Cartridge Filter Adapter

thingiverse

My Home Depot/Lowes used to carry cartridge filters for my MSA dust masks, but now they only seem to carry the 3M brand. This lets you use the 3M style cartridge/filter on an MSA mask. To do this, just take apart the filter that comes with the MSA mask: (P100) Micro Low-Profile. I used needle-nose pliers to remove the insert that holds the paper filter in place. Next, print the adapter and silicone it into the spot where you removed the original filter. Printing with supports is not necessary but will help with the overhangs on the 3M end. WARNING: Use this at your own risk. I don't know how well it works compared to a real cartridge. This was meant to be a test to see if I could create this in FreeCAD.
