faceshield

# Face Shield
The goal of this project is to create a low cost, high quality, reusable face
shield that can be quickly deployed.

This face shield is based on a previous design by Mike Doell (@mike_doell). This design was reimagined in FreeCAD and iterated upon by Jake Bender with help from Glia's team of collaborators, designers, and testers, as well as engineering and design input from [Mosaic Manufacturing](https://www.mosaicmfg.com).

This faceshield is currently available at the [Glia Store](https://store.glia.org).
