Car Mobile phone holder

I created the magnetic mobile phone holder for car by using "Ball-in-socket" mechanism

Why ball in socket mechanism ?
Ball in socket mechanism has three degrees of freedom, which is very helpful to use the mobile while holding in a holder, we can either rotate and forth front and back the holder , so I chosed ball in socket mechanism…

Why magnetic holder ?
To reduce the human effort , I chosed magnetic holder, if we magnets to hold the mobile phone means we can easily access the mobile with holder and it's user-friendly.
