Ball joint for car QI phone charger holder

The ball joint of my car phone holder was worn out after a few months.
I made a new one using 3D Builder.
The type of car holder you can see in the picture.
You may want to slightly adjust the diameter to fit your mount, it is easy, you can do it with any slicer.

I added the whole support, re-designed to fit my car, where there are not many plain surfaces and I cannot use the air outlets. 100% infill, PTEG. Just fix it with a double layer tape. It works great for me. Included f3d file.
