This is a face shield that attempts to simplify the shield of other common 3d printed masks by using a standard comb ring binder punch instead of laser cutting to allow dozens to be assembled in a few hours without highly specialized tools. The current revision has a pair of loops allowing 1/2" to 1" elastic bands cut to 13" to be fed through the holes like a belt friction fitting eliminating the need to tie the material, and allowing continuous adjustment for improved comfort. Additionally the 0.25" band version of the design accommodates the more common 0.25" elastic material. the 0.25" band is more comfortable and prints ~13% faster at ~13 grams so it is recommended for indoor environments while the 0.5" version is more suitable for the outdoors.
By eliminating the double band of other 3d printed shields we resolved the issue of the top of the shield being open to the air between the forehead and the shield without greatly increasing the print time or geometric complexity aidi
