Horror mask

Mask prototype made in spare time. Seems works fine but you could have to refine with sand paper in some parts for optimal result. Take care the scale factor. I made this in Maya units.The rubber parts should be print with other filament (rubbery). the optimal solution is take some parts of 3M mask at the end of life. Also the exit valve you can take on that. Ok, isnt all in 3D print but is funny :-)
Thanks, Enjoy!
