Accepted answer

Sure! Here's the description in English:
You want to redesign a wind turbine so that the blades are separated and fit into the central part, with a total of 4 blades. I understand that you will upload the STL file for me to assist in making the necessary adjustments.
Once the file is uploaded, I will provide more specific guidance on how to separate the blades and redesign them to fit into the central part of the structure. Feel free to upload the STL file, and we'll proceed with the work!
