Abstract: A collapsible device in a waffle structure is disclosed. The collapsible device includes a plurality of panels, each having an outer edge and elongated slots. Each of the elongated slots extends from the outer edge towards a central portion of the panel. The elongated slots receive intersecting panels such that the plurality of panels intersect, interlock, and create a waffle-like structure. The plurality of panels is configured to move pivotally to articulate the plurality of panels between a collapsed configuration and an extended configuration. The collapsible device is used in various applications, such as fidget toys, furniture, light fixtures, and other industrial applications such as jacks or material conveyors, or any application that benefits from flexibility or increasing or decreasing the size or length.
