I tend to think the design is actually pretty good IF the posts were
more flexible and tougher. If the post flexes, it can accomodate
slight misalignment without undo stress on the panel.The friction fit
of the ball in the socket doesn't change with misalignment either. The
method also doesn't require any clearance between adjacent panels
since it comes straight off the pins.

If the posts and balls are metal, the panel sockets are going to crack
because there will not be any give in the shaft. If the ball and shaft
is replaced with a solid pin, the panel sockets will get damaged
because the socket will have to flex to conform to the pin.

I like the idea of an X cut in the ball.
