my take on these would be make them out of soft metal,(Al) thread the post
holes and use a threaded post with a
recess for either a "O" ring or tubing to hold the panel.

I think there are other ways to produce this than a one-piece molding, if the
aforementioned RC balljoints aren't suitable replacements.
I'd take some nylon, acetal, HDPE etc. threaded bar stock (plenty on eBay) and
make a form tool for the ball and post combined, then knock them
out on a lathe. Tap the block for the thread. The most time-consuming part in
this would be the form tool profiling, but being soft material
you could get away without the need of grinding a HSS toolbit.
I've got some nylon bolts and my trusty Unimat lathe so I may give it a go to
see if it works.
