This face-shield assembly has been modified from the design released by PRUSA to incorporate ready-made face-shield materials commonly available in the US: "Clear Easy View Plastic Dividers; Avery 16741" commonly available at office supply stores. It is a quick ~2hr print and can use hair ties, head bands, or other elastic bands to secure it to your head. If printed in PLA, the purchased plastic bit can be discarded and the printed bit can be sanitized with Isopropyl Alcohol and re-used.
With 3-hole plastic dividers, there is no need to procure, cut or find the pre-made face-shields, dramatically simplifying providing PPE to your local first responders and medical professionals.
