3M Air-Mate PAPR Hose Fitting with Flange and Mounting Holes

thingiverse

This is the 3M Air-Mate PAPR Hose connector that has already been posted by another more talented user: paulschonfeld. All I did was add a flange for better mounting and some asymmetric holes because I'm not skilled enough with Tinker CAD to get them symmetrical. When printing, be careful with the flange. I lowered it so it makes more contact with the hose connector, but my mark I models still had the flange break off. Also, be aware that this is a copy of a 3M design and is compatible with the 3M Air-Mate PAPR. I assume no responsibility for your use of this design; use at your own risk. Be careful to properly fit-test any protective equipment you may use this with, as any good design is only as strong as its weakest part.
