1 inch ball for ball and socket

I needed a base for a phone mount.

The post and base is left hollow to add a metal support rod in. I am JB welding a bolt in place.

The Ball with out the base for a 3/8th connection bar. I printed two and am adding the bar in between.

I will include photo once I am done assembling them. I also have a version with a shorter post. although it it very east to edit in Sketch Up.
