This a remix of 2 separate pieces.

First is a Pop Socket (https://www.thingiverse.com/thing:2560011)

Second is a ball and socket from an articulating arm (https://www.thingiverse.com/thing:2069128).

I love using popsockets on my phones. Unfortunately most "tripods" or arms don't take them into consideration. This was a simple merge and cleanup.

Using prusa-slicer, painted on supports where needed.

since these are meant to be structural in nature, printed with 5 perimeters and 50% infill at .2mm layer height. Could probably do different but thats what worked for me.
