This site is to help anyone with a 3D printer make simple face shields using readily available materials in the US. The design is based on the original Prusa Face Shield and modified to print faster, use Letter sized plastic sheets and a standard 2-Hole-punch for spacing the holes out. This is a very basic face shield, it is far from perfect, but it is something that anyone with a hobby-grade 3D printer can produce at a reasonable rate.
The frame is a slimmed down version of Prusa's original design. I recommend printing these in PETG. 2 frames can be printed on a standard full size printer in 1.5-2 hours depending on speed and nozzle size.

While the frame can accommodate a variety of elastic bands and straps, a simple solution is to use Non-Latex 117B Rubber Bands.
The shields are made of standard 12MI PVC Binding Covers, the holes are punched using a standard 2-Hole punch (set to 5" wide paper).
Letter Size PVC Binding Covers (10-12 Mil)
Cut the rubber band and tie small loops at either end. Thread the loop around the frame "buttons"
Set the hole punch to 5" wide sheet and punch holes from both ends of one of the long edges. Insert the frame's notches into the holes starting from one end and working towards the opposite. The last one will require a little flexing of the frame.
** Please take care when making and handling these shields. Wear gloves and shield yourself to avoid any contaminants getting on the shields.
Hospitals may be overwhelmed dealing with the COVID-19 outbreak, it isn't always easy to find the right person who can confirm the need and coordinate pickup/delivery of such items. I have had luck reaching out to hospital staff on Facebook and asking them directly. Search Facebook for your local hospital and it should help you find people who work there and can steer you in the right direction.

Quick to print Ear Savers! These have been designed with printing speed in mind. Please use PETG due to how thin they are.
