My partner wanted this hook for her car. I made it to fit her 2003 Jetta TDI wagon. It will likely fit other cars as well.
The hole is 14.5 mm. The hole center is 55mm from the perpendicular line. The hook part is 70mm. (see the attached image)
I attached STEP and F3D files for your editing pleasure!
