This is a simple phone holder. I made it dimensionally for an iPhone13, but I think other phones will also fit - I'm also attaching the dimensions for better decision-making.

A steel plate needs to be printed into the holder. The plate is an ordinary roofing sheet with a thickness of 0.5 mm and dimensions of 40x40 mm. It is available everywhere.

The holder then fits the classic magnetic target on the ventilation grills in the car.
Printed in approx. 1.5 hours.
