20mm x 20mm square profile / pipe thighy

Not the connection Ball, but the same idea.

Without the seat part (stil in progress) you can construct a chair.
The idea was to show a chair with a net made out of 20mm x 20mm square bars, which hung in between a frame. but since I had overwritten a file while exporting seperate STL file I lost everything and this was the stuff that could be saved. But hey it was my own mouse click. :-/ Unfortunately the file could not be recovered.

I hate the end result, but maybe you like it... T
