Remix Parts: Fiat 500 / Abarth / Alfa Romeo Phone Mount for GPS plug

I used russiancatfood's great design (https://www.thingiverse.com/thing:696271) and remixed the moving ball to hold a new part, you can easily slide a vent-mount phone holder on.
Besides my two files you need to print the main parts of the holder from russiancatfood (see image).
The thinner holding part has two pins that should slide into the holes of the sphere with some force. The center screw holds all parts together with the inner ball and can be tightened after you found the right adjustment for your phone.
I printed it in ABS and it works reliably for nearly two years now in my Abarth.
