New Front Insert For Breathing Respirator (4348569)

thingiverse

I liked this design, however upon printing I find that the fins on the front insert are too thin for my liking and prone to damage, this is my fixed version, it's not perfect but it provides more stability and still keeps a sharp front edge and the profile is pretty pleasing for what it is. same dimensions are here and the inserts still fit as they should. I have also created an inner insert for the front, not sure if it's missing for a reason or what, but I created one and scaled it for tolerance to fit.
