Open Source Face ShieldV1.1

The Open Source Face Shield is a low cost, medical face shield designed to be quickly made using almost any flat material fabrication equipment (laser cutters, rule dies, drag knife, CNC punch, etc.), or even scissors and an office hole punch from any clear flexible material.

It requires no hardware or 3D printed parts, just two pieces of flexible clear plastic and an elastic band.
