Flip Up hack of R3 USA Version

This is a very rough but functional hack of the R3 USA face shield. A neonatal nurse asked me if there was a way to make the shield able to be lifted up for close examination work. This design is all one piece and thus quite rugged. It has to be held in the upright position with one hand to keep it from crashing back down. If it proves useful - someone with more skill, please clean it up and make it look nice. Print instructions No supports needed.
