Steam controller magnetic phone holder v2 (ball and socket joint)

Update: A new model is uploaded, the ball is raised by .5", this should work better for larger phones.

In case you didn't know, you can connect your steam controller to your mobile device with an OTG cable. Meaning you can play controller supported games or any emulator on your phone.
This ball and socket joint has the same spec as my other design http://www.thingiverse.com/thing:2095346, so if you have already printed the socket and nut you won't need to print them again.

The ball and so
