iPad (gen 8+9) mount VW Passat B8 rear seats

The holder is printed in three parts, without support. Originally I wanted to use ASA or PETG, but due to warping I had to change to PLA. But the angle holders are printed in PETG.
The parts are connected with M3 screws, the angle holder is prepared for a bolt or a threaded insert. Of course you can also glue everything together.

Update: 
Don't use PLA, one day in the hot summer sun and it shrinks!
