OpenSourceGuard - 3D printed face shield with less material

Here is our 3d printed face shield design. It does only requires a regular rubber band to secure it on head. So no need to find elastic headwrap.

You only need a 5 hole puncher to punch the holes for plastic shielding like this one: https://www.amazon.com/gp/product/B00006JNWR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
