Nose and Mouth guard USE AT OWN RISK, I hold no responsibility for the effectiveness of this device. Freeware, Share and Share alike, feel free to modify, reproduce and sell. The shield can be printed out of Plastic PLA (ABS will leach toxins), or out of Flexible, The Flexible is more comfortable. You will need to print with support material. I would use 10% support material, and overhang angle at 60%. The more support material you use the longer it is going to take to print. If you are having problems removing the support material, try lowering the nozzle by temperature, or adjusting the Z distance. This shield is scalable, a uniform scale in the printing software will make it bigger or smaller, a non-uniform scale will let you to make it taller, shorter, wider, or longer.
