My wife needed a way to store her earring collection so I designed this rack. Each layer will hold 18 pairs of earrings with a tray to hold small items like earring backers, rings, etc. The upright rod is 1/4 inch dowel rod bought at the local hardware store. It would probably work better with 1/4 steel rod. The lock rings use a M3x8 hex screw to lock the ring to the upright rod at the desired height.

Next Version will probably have a thicker rod.
