Buckle for Face Mask

thingiverse

Because of COVID-19, face mask is a must when everyone go out or go to work. Ear hurts when you wearing a face mask for a whole day, especially N90/N95 ear-hook face mask. The buckles are designed to hook the face mask belt and free your ears. **How to use:** a) One basic buckle is roughly enough. Put the basic buckle behind the head to hook the face mask belt. Every basic buckle has 3 pairs of hooks, and use different pair to adjust the tension. b) Two basic buckles and two extended buckles are almost perfect. One basic is placed behind the head, another basic buckle and two extened buckles are connected together and placed on the top of the head. Head-mount your ear-hook mask and fully free your ears. **Tips:** a) If the length of basic buckle is too short to hook the mask belt, addtional extended ones can make it longer. b) If the buckles fit well with your head, you may cut other hooks with a scissor.
