I normally publish and update all my models at MakerWorld. They are only here on Printables to keep the accounts consistent.
Please download the newest version here at MakerWorld.
Seems to fit for most models that look like a tennis racket. Eventually you have to scale it.

In my first attempt I uploaded a wrong file. Sorry for that!
Now I uploaded the right STL.
The author marked this model as their own original creation.
