Comfortable ear saver (especially for people with long hair)

thingiverse

If your ears start to feel uncomfortable while wearing a behind-the-ear mask, or the elastic on your mask is too loose, this simple fix will help get your mask fitting properly again. Measuring six inches long and 1mm thick, it's printed with PLA material that's surprisingly flexible. Most ear savers I've seen have pointy parts that tend to get tangled in my hair. However, this design can be worn comfortably around the back of the neck or across the back of the head, keeping your mask securely in place without any sharp edges.
