COVID-19 Face Mask

This face mask provides an excellent fit thanks to the four sizes once it's outfitted with a weather sealing strip on the inside. It supports removable filters and has elastic strap attachments with loops that allow for easy readjustment.

The shape of the shells were inspired by the LaFactoria3D mask, but I completely redrew them, made them more sturdy, included some comfort tweaks and added an additional size. https://www.thingiverse.com/thing:4225667
