The following requirements were used as the basis for this design:
1. Provides the minimum protection from direct splashes to the face.
2. Utilizes materials that can be procured from office suppliers.
3. Requires no specialty tools to manufacture.
4. Packs Flat for shipping.
5. Assembly instructions to deploy from flat pack to wearable less than 3 steps long.

The resulting design is a face shield made only using transparency sheet, sissors, and a hole punch. The included document is made to print the design directly on to inkjet or laser compatible transparencies for cutting the pattern. It can also be mass produced with a die punch or cnc cutter.

The shield is 3 parts: Shield, forehead strap, and elastic strap.
It assembles as a flat pack, and can be deployed to the wearable configuration in seconds.

This was inspired by the many projects online to design a face shield to help protect our nurses and doctors during the PPE shortage. This can be made with the fewest possible materials: printable transparency sheets, and a rubber band. It is comparable in functionality and protection to the commonly available disposable face shields available in most hospitals that are constructed from a piece of foam and a sheet of plastic.

This design can be assembled flat and many can be shipped in an envelope.
