This face shield, developed as an open source stop-gap for the PPE shortage affecting front line workers world-wide, was designed to be laser cut. The intention for this project was to develop a face shield that can be produced relatively quickly (around 5 minutes per shield) and to use minimal materials, while still providing effective protection from droplets.
All files, including a DXF for laser cutting and a bill of materials, can be found on the Flat-Pack PPE GitHub:
