Flat mount sunglasses clip for use anywhere you need to store your glasses. I put two over head in my center mount in my jeep. Works perfect! Adhesive backed foam is required inside the clamping faces to keep glasses secured and so they don't scratch. Any small piece of wire is required for the hinge pin. A paperclip might work, I used a piece of weld rod. Just drill to the size you need. I used ABS due to the locking mechanism but PLA might work as well.
