3M Mask (3D print ready)

A mask with 3M adapters compatibility with 6000 series 3M filters, 3M inhalation valves(6000), 3M inhalation port gaskets(6000), and exhalation valve pads(31mm)

This design adopts the 3M adapter so the users can take advantage of most of the 3M filters/cartridges in the market. I added an CO2 exhaust valve that uses standardized rubber pad you can purchase online.

This design uses modular and adjustable clips so users can find better fit and only replace broken clips without replacing the whole mask. (Stress tested with a safety factor of 2.8)

NOTE: 

• Use the included .txt file to find standard parts to purchase. (i.e. valve port gasket and pads)
• This is not to replace proven PPE but an alternative if you can't find any.
• Designed to work with 3M accessories only.
