This work explores the design, modeling, and fabrication of large-scale conical Kresling origami structures with the goal of achieving bistable mechanical behavior. While Kresling origami has been extensively studied at small scales, applications at larger scales remain underexplored due to increased material challenges and deformation demands. This project develops automated routines in AutoLISP for generating crease patterns and truss models within AutoCAD, enabling rapid iteration and precise control over geometric parameters. A fabrication method utilizing 3D-printed components and silicone rubber joints is introduced for creating both cylindrical and conical Kresling cells. Through multiple design and fabrication iterations, a bistable conical structure is successfully realized. Analytical models are developed to characterize the bistable states based on geometric and energy considerations. The results highlight the feasibility and limitations of scaling Kresling structures, and future improvements are proposed for enhancing joint durability and expanding design automation.
