Ear saver

Print two and connect them with a hairband. Hook the ear loop from the mask on the ear saver.

It's better when you wear the mask, the ear loop goes above the ear, as shown on the image, so that the mask doesn't slide down.

This will help you from the torturous pain applied on the back of you ears and the hair band helps fit different sizes of people.
If too loose, you can tie the hairband in the middle to tighten the tension.
