When the pandemic hit in March 2020, masks were suddenly impossible to find.

I teamed up with an autonomous systems expert in Germany and the founder of a 3D-printing startup in Tennessee.

A team of three. One monumental task.

Could we create a reusable mask anyone with a 3D printer could make? Using any filament? Anywhere in the world?

We did it in six days and released the files for free.

A Mask For All came in different sizes, could be sanitized and had a filter pod that worked with materials people could find at home. We also created a clear version for people who rely on lip-reading.

In the first two weeks:

11,000+ website visits
Thousands of downloads
Coverage in more than 140 articles
Masks made on five continents
Zero media spend

We never met in person. We saw something that needed doing and did it.
