Any thoughts on the stability of this cage design for my desk (30" x 60")? I plan to mount my studio light(s) as well as two cameras—one forward-facing and one downward-facing. I may even modify it so my speakers are raised off of the desk and potentially mount my monitors as well.

I plan to clamp the cage to my desktop with four of the pictured clamps. I plan to drill holes into the legs and pass the clamp pin all the way through. I've also considered having a horizontal pipe at the base with t-mounts and just clamping through the opening. I'm leaning toward the former to have a bit more desk space.

I know I'll modify it once I get my hands on some product, but I'm trying to get a rough idea about what to order. The structural kit is looking like a decent start for at least this project.
