Hi Everyone, I used Alibre Atom to model a mask. I was really peeved that most of the ones online are pure marketing or do not include the original file. This one seems to seal, although I am printing the first one with straps hooks right now. It is very time consuming so I am asking for some help. Does anyone want to check out the model and suggest any edits? Does anyone want to model any modular filter housings? Some notes and links to the file on git hub are in the attached text file. Any help or suggestions are more than welcome!
