Hello James, Welcome to 3D Printer Chat. I’m sorry you are having so much trouble getting help with a necessary medical device. I am trying to understand a little bit more about what you’re asking. Are you looking to have a cover that goes over your nose that opens and closes via a hinge at the bottom? How would the adjustable wrench come into the design? I imagine you are looking to use a mechanism similar to how the wrench jaws open and close to open and close your nose mask. This is all speculation on my part though. Could you give me a little more detail about your design? Possibly some sort of drawing or illustration showing me what you’re talking about.
