I created two sizes, once 130-200mm (5.1-7.9 inch) for "normal" devices and 190-280mm (7.5-11 inch) for large tablets. I recommend using PETG as it is much stronger than PLA. Also, it does not deform easily in a hot car.
The holder including tablet can be easily removed while driving (if the kids have pressed something wrong again ;) ) and you have to get it to the front.
All moving parts can be arranged so that they can not loosen during use. In addition, the mount can be screwed tightly with the assembly tool and put under tension.
