Stroller phone holder

I wanted a phone mount for the stroller and couldn't find one so I modified an existing bike mount. The main issue with the model I based this mount on was that the top bar of the stroller is much too thick to mount on and when mounted on the side bar the phone orientation is wrong. I tried many variations and settled on a very simple change to change the orientation.

Instructions: there are parts with ball/stroller/holder in their name. The ball connector and ball screw connect the stroller mount parts with the phone holder parts.
