Phone holder with screws?

[groundcontrol]

Bought the OH an Audi A3 (2004) recently and she has nowhere for her phone. There's three holes around the bottom of the centre console where I guess a previous older style mount has been installed.

Does anyone know what these are called or who makes them? All I can find is stuff you stick to the screen which is no good, if I can plug the holes with another mount I'd rather do that.

It's an iPhone 6 if that helps.

Thanks.
