A storage shell includes sidewalls and rails. The sidewalls each extend between two others of the sidewalls to collectively define a chamber therebetween. The sidewalls create a plurality of intersection lines each being defined along a boundary between two of the plurality of sidewalls. The plurality of are rails each coupled to and radially extends away from a different corresponding one of the plurality of intersection lines relative to a center of the storage shell. Each of the plurality of rails is formed with a Y-shaped cross-section. Related storage and organization systems, and methods are also disclosed and provide additional advantages.
