UPDATED Version 9 can be found on http://github.com/theantidoteftc/MaskStrainRelievers. The Thicker version is recommended for the Ender 3.

The Mask Strain Reliever sits at the back of the head when using surgical masks or any other face covering that typically catches behind the ear. The strain reliever redirects the strain from on the back of the ear to behind the head, to alleviate pressure caused by the prolonged use of these masks. The "REAL HERO" embossing shows our gratitude to those who are working harder on the frontlines to help combat the pandemic.

The latest version (V7) Mask Strain Reliever can be found in the Github repository located here: http://github.com/theantidoteftc/MaskStrainRelievers
