Create a design for a minimalist dirt bike stand constructed entirely from aluminum tubing or sheet metal. The stand should feature a wide, flat top platform, ideally positioned at a height suitable for supporting a dirt bike specifically under the engine case. Ensure the design reflects appropriate proportions for a dirt bike stand, avoiding any bulky or overly delicate elements. Emphasize stability in the design, indicating that it should convey a sense of robustness and the ability to securely support a dirt bike. While maintaining minimalism, the stand should also have an element of visual appeal, making it not only functional but aesthetically pleasing. If possible, incorporate modernist design principles for a more targeted aesthetic. Before generating the image, conduct a self-evaluation of the design concept to ensure it meets the following criteria: 1) Entirely made of aluminum, 2) Flat top for engine case support, 3) Proportional and stable, 4) Minimalist yet visually appealing, 5) No visible fasteners. Proceed with image generation only if the design aligns with these instructions.
