I have added a mannequin head for sizing
This model is not 100% correct and is a work in progress so I will be fine tunning this over time. I have been working on this model for some time now, and tired of not seeing a descent printable reveal helmet. I havnt printed this yet, so if anyone does, please post so the rest of us can see how it turns out. Underneath breathing apperatice is a spot for a 28 mm speaker for breathing affects. Top, bottom jaw and dome are held together by magnets.
