This is an IPhone 7 holder. It should also work with an Iphone 6 or 6s (without plus).
The part was designed to hold the phone with a silicon case so you dont need to remove the case to put your phone in.
The part can be mounted via three 3mm holes.
I also created a car holder for this part. If you have a VW group car with a phone preparation you can find the perfect baseplate for this holder here:
