Adjustable phone mount arm with ball joint

Adjustable phone arm with ball joint connection so the phone angle can be adjusted. I used this arm to mount my phone between the monitor and my steering wheel to use as dashboard for added immersion. 

NOTE: This is the joint only, use super glue to assemble the ball joint. For other parts of the arm please see https://makerworld.com/en/models/931233-couch-sofa-armrest-organizer-adjustable-phone-arm
