Abstract: Compartmented assemblies related to customizable storage compartments. A bottom panel, side panels, and divider panels may be configured in any combination to form a compartmented assembly with a primary compartment comprising at least two sub-compartments. A method of designing and constructing compartmented assemblies is described. A graphical user interface may be used to format a design which may be transmitted to associated machinery for automated cutting of the component panels. Series of notches, tabs, and apertures are used for mating adjacent panels to one another. Adhesive may be inserted into joints for securing the panels.
