• The snap-on face visor/shield was designed based on feedback from the users, mostly frontline medical care workers and doctors faced with PPE* shortages

• The goal of the project was to design face to address the following requirement points

  • Designed for reusability, ease of maintenance and sanitization, with less to no hard-to-reach nooks that trap contamination

  • Easy to install and use, with removable/adjustable front A4 transparent sheet orientation and height

  • Able to be used in conjunction with prescription eyeglasses as well as masks/respirators (e.g. N95, FFP3)

  • Avoid punching holes in the plastic sheets, a possible contamination entry point, and reduce manual work of preparing the plastic sheets with a hole puncher

  • Comfortable to be worn for long hours, without adding sponge which is easily contaminated and unable to be sterilized effectively.

  • Balanced with ease of printing with a range of 3d printer models and materials (PLA, PETG, ABS). 

  • Optimized for smaller footprint for printing on small form factor home printers (200mm x 150mm beds) 

  • Not significantly longer to print with comparable designs and size

  • Options for protecting contamination from above as needed with a top cover component
