I have a MultiBoard mounted to the underside of my print desk, in which I wanted to be able to mount some things up from under the desk, like a Panda Touch, and a BTT Pad 7.
 

The MultiBoom seemed like a great place to start

But, in order to get any vertical adjustment in my setup, I'd need a piece to rotate the orientation of the boom arms.

It is a bit awkward of a piece. I modified it directly in Orca rather than loading it or redrawing it in my CAD software, just to get something done.

Hopefully others can find this useful.

If you mount to a MultiBoard under a desk, I highly suggest gluing the swivel mount from the original arm to keep it locked in place.
