A storage shell includes a plurality of sidewalls to collectively define a chamber therebetween. A first sidewall defines a panel and a track. The panel defines an outer perimeter edge, an exterior surface, and holes extending through the panel. The track is coupled to the panel and includes a first rib and a second rib each extending from the exterior surface. The first rib is positioned inside the outer perimeter edge. The second rib is concentric with and shaped similarly to the first rib. The first rib and the second rib each separately border each one of the holes where each of the holes is formed between the first rib and the second rib. Related storage and organization systems, accessories and methods are also disclosed and provide additional advantages.
