This is a remix of the DtM 3.1 face shield with a print-in-place hinge to allow the visor to flip open. The shield profile is also modified to wrap around the sides more (similar to the DtM 4.0 injection mold version shape). As a result, there are tabs added on each side to help secure the transparent material to the shield profile. A non-hinged version with the same profile and side tabs is also provided. Mounting system is the same as the original, standard US 3-hole punch. As with the original, the Prusa RC3 bottom reinforcement can be used as well. Recommend using 8 mil or thicker material (i.e. report covers) rather than projector sheets for better rigidity.
