Ear Saver for any masks

thingiverse

For those who wear masks daily, soreness in the back of their ears is a common issue. After hours of wearing store-bought or handmade masks, blisters can even form. This clever design provides relief from pain. To attach them, use a hair tie like Goody's Ouchless Medium Hair Tie, which has no metal. Alternatively, a simple rubber band will also work. If you need extra length, just interlock two ties.
