Mercy Face Shield 3D Printed face shields for anyone in need. Please pass this on and contact us if you are a healthcare worker. PLEASE NOTE- During the COVID-19 emergency, we are providing these shields on a donation basis. After working with many Local Hospitals we have come up with a quick printing Face Shield. We had found that the top must be closed for the face shield to be acceptable. Another thing was that many shields fitted too close to the face, so we moved the shield farther away from the eyes and nose. You can easily wear a pair of glasses under this shield. One other thing was to make it work with any 3-holee punch, and the shield should be able to be removed and reassembled, for cleaning. This is our latest Version but we are still working with healthcaree professionals to find the perfect working face shield. Please download MercyfaceshieldV9 our latest version. It is the latest. Please contact us with any questions and stay safe. We use Fellowes Crystals Clear PVC Binding Covers on Amazon https://www.mercyfaceshield.com/ This website has assembly instructions.
