I cut this out with a laser cutter. I then folded it into my best guess of a decent shape. I used a soldering iron for a quick and dirty way to attach the sections. I trimmed the point off.
Just a rough idea using the dimensions of the face shield. Could be a add on or extend the shield to include the shape. If this is a problem worth solving then I thought there might be someone more suited for the design of this. @RealCarlRaymond ? Or maybe someone with Packaging at MSU?
I used .004" dur-lar
