Vacuum Formed Face Shield Visor

Inspired by the Prusa shield visor 3D print, I wanted to try designing something with even fewer parts, and cheaper to make. Obviously it will not be as comfortable as commercial ones as it's not adjustable, but it might make up for it in quantity. Since everything is tapered, you can stack multiple into a space efficient pile to make supplying to hospitals cheap and efficient.I do not have access to a CNC and a vacuum forming machine, but it would be by far the most efficient way to fabricate these, probably fabricating hundreds per day at a minimal cost. If anyone has access to a CNC and a vacuum forming machine I would love to see this design tested out. If someone can use a CNC to fabricate the mold from wood or even rigid foam, and try vacuum forming it with 0.75mm or 1mm PETG sheet, it would be amazing. 0.5mm might work, but I'm afraid it will be stretched too thin around the edges and not hold up. The triangular extrusions on the sides are meant to be cut into about 7-10mm in to act as a fixture for a rubber band to be hooked, or tied to, depending on how it's cut.I can adjust and make changes as needed, just leave a comment. Please share!
