Hole Punch Face Shield
This is Personal Protective Equipment (PPE) for use in healthcare we can craft at the space for emergencies and supply gaps. It is a barrier to prevent droplets coughed/sneezed by one person, from entering the eyes/nose/mouth of another person, to prevent spread of disease. If using a respirator (like an N95 mask) is necessary to prevent infection, a face shield is likely also necessary for protection of the eyes/face.
It is composed of three pieces: a headband, a top shield, and a front shield. All pieces can be quickly cut on our Laser Cutter. The headband is cut from 1/4" Acrylic. The front shield mounts on the frame, and is the transparent, stiff plastic that serves as the barrier.
The front and top shields are ideally cut from sheet extruded Lexan or Mylar of 5 mil or thicker. Common transparency sheets also work. The design is compatible with 3-hole punched material, meaning that anyone with common office supplies (3-hole punch and transparency sheets for overhead projectors) can make their own front face shields.
There's a request to slightly increase the gap for the outer tabs for a more secure fit for the shield. This hasn't been done yet.
