Sprial wind blade

This model is a Spiral Wind Blade, applied in the real world for wind power generation. Its unique blade design allows it to rotate easily even in low wind speed environments, enabling the generator to start operating and produce electricity. This uploaded version is the second iteration after my practical testing, improving the issue of blade rotation in the initial version. In the first version, the blades needed to be clipped into the frame, but the high friction made it difficult for the blades to rotate. Therefore, in the second version, the clip structure was removed, and the blades are now placed directly to ensure smooth rotation. However, please note that if the entire model tips over, the blades will separate from the base, so caution is advised. ◆After printing is complete, there will be some small supports on the frame. Please carefully and thoroughly remove them, as any remaining supports may cause additional friction and negatively impact the blades' rotational effici
