In this study, we propose a method of forming various three-dimensional objects by combining and bending flat
modules processed by a laser cutter or CNC. When the arms inside each module are connected by pulling, the module is transformed into a curved surface, and the curved surface changes when the connection position is changed. There are multiple types of modules with different arm arrangement patterns, and a three-dimensional object is formed by combining these modules. When the arms are disconnected, the module returns to its original flat surface, thus reducing transportation costs and allowing reuse of modules. Since anyone can freely create the shapes using readily available materials, it is expected to be implemented in fields such as architecture, fashion, and educational tools.
