Well, I guess since it's my own thread no one will get mad at me for hijacking this one, but here's something I made from PVC years ago:
It's a Table Top Perch I use when I take Rocky somewhere
Folded down, it's a compact & low perch for the table top....
...or you can remove the upper crossbar and fold the legs up...
...then you put the crossbar back on top for a higher perch...
...then rotate the middle bar (does that make these "rotator cups"?)...
...and finally, you simply install the Parrot on top of the perch!
He has a food dish and a water dish right there in front of him.
