Custom phone mount using LocLine 3/4in ball and socket adapters and Pop Socket Glitter (much thicker than original version) or a slot for Flygrip phone stand. That way the mount can support phones using either type of stand and the locline adapter makes it easy to use in other situations like mounting in a car or in an office.
