MultiBoom Arm Rotator

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 starthttps://makerworld.com/en/models/418897?from=search#profileId-321462But, 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.
