Ryan Chen's COVID-19 Face Masks

Description

Here are the parts and instructions to 3D Print the face masks that I modeled and printed in April 2020. The "Ryan Shell" and "Steph Shell" are the two mask types I modeled based on the 3D scans of my face (Ryan) and my wife's face (Stephanie). Stephanie has more pronounced cheekbones and a wider jaw, and I do not - my jaw line is more narrow. I recommend printing at a layer height of 0.15mm. My masks were printed on a SeeMeCNC Artemis 300 with Atomic Filament. I have included instructions as JPG images and a PDF. The parts should snap together but you should use an acrylic glue (clear medium bodied solvent cement) or weld the pieces together using a soldering iron. See instructions for more details. For the rubber seal I experimented with these options: 1.

I know that sounds weird, but it's a real thing that we use to use a couple years ago.
