I modeled this support to use in my car, a Volkswagen Saveiro G3.
As I had difficulty finding a support for the iPhone 13 Pro Max with case, I am making this available so that you can use it as a basis for your project and develop as needed.
If you use your cell phone without a case, it will probably be a little loose on the support.
The hole is for an M3 screw, so that you can attach the support to a second part that you will model according to your needs.
The author marked this model as their own original creation.
