adjustable tablet phone holder

I put a 0.5 mm set on the pivot pins.
Everything is printed in one block.
I made my impression with a 0.6 mm nozzle in PETG, I had to force to put the parts in motion but after that everything works.

There are 4 degrees of operation (15°, 30°, 45°, and 60°) with a 32mm shoulder as shown in the diagram. I finally doubled the dimensions of the diagram to have a larger and more robust part.
