 The downside of this method are that firstly these mask tend to deteriorate over time and with use as they are ment to be single use item, however they are obviously swapable so they can be switched when unsusable ; and secondly that the height of these mask and the length of the adapter puts the majority of the mask weight far from the face and thus a bit unconfortable, espacially under quick head movments.

 **WARNING : _Please don't use a 3D printed cartridge (or even our mask) in life threatening situations !_** Or at least understand the inner working of gaz mask and test your gaz mask (_especialy its fittment to your face_) before using it.

 There also exist 3D printed adapter from this standard to other standard gaz mask connector if you search on 3D printing site.
