Cube Wall Pipe Join Star and Hook Receiver

We are still using 1970s era cubical walls at my office. The wall joins and corners are a pipe, a "star" at the top, a metal hook through the "star" and a the pipe sits on a metal hook at the base of the wall.

This original "star" allowed for 45 deg walls and was made of plastic. This version allows for straight wall joins and corners. I printed the prototypes in hot pink... because my wife made me print ONE THING in hot pink and I have too much of it.
