For face shields, I noticed that the hardest part to source was the clear screen, so I designed an alternative optimized to be made with readily-available materials. I went with the omnipresent, 2-liter bottle for the screen and a hair tie or rubber band for the back. No other materials necessary. I also made a cutting guide and holding pins, so that the 2-liter bottles can be perforated quickly and precisely.
