In the day and age of COVID-19, it is a sad reality that healthcare workers, essential workers, and the general public are increasingly being required to reuse life saving PPE that are in short supply.

In light of that, I have made an enclosure that will protect a normal size N95 face mask. The current size allows for the mask to be placed inside of a paper bag, then placed into the enclosure for protection in a bag or backpack until the next reuse. The enclosure remains breathable to allow the mask to dry after use and is lightweight while only being slightly larger than the mask itself.

Keep in mind that this object will become dirty and will need to be cleaned as required. Prusa Research has tested several ways to clean 3D printed parts. Their tests apply to PETG so your mileage may vary with the use of other materials. Follow the link below for the most up-to-date information from their tests.
