I am continually refining versions of these models and uploading new files as they are completed. This repository contains models that I have modified, created or sourced from other sources, all of which I believe have value. For face shields: Use A4 binder plastic or projector plastic, combined with a hole punch to create holes, the pin spacing matches that of a standard paper hole punch. I am working closely with the Montana Mask project, led by doctors who conduct thorough testing. Instructions on how to build the mask are available at makethemasks.com. As the Australian Coordinator for this project, you can find a list of coordinators there as well. Please note that this is a DIY PPE project, and any use of these models is entirely your responsibility.

Be aware that this mask design is not meant to replace standard protective gear like N-95 masks or surgical masks when they are available. Use of these 3D printed masks has not been fully tested and has not been approved by federal or state authorities.
