sorry for the long link

With amazon links the only thing that matters is the /dp/B072N84V8S so this link is equivalent:

https://www.amazon.com/dp/B072N84V8S

it stayed in place but it couldn’t spin if you know what I mean 😭

We don't know what you mean. Does the shaft of the motor (generator) not turn? If not, then it won't matter how you attach the blades. If it does turn, then why is it not turning the blade hub?
