Quad HP-USB video adapter monitor post mount

Wanted a tidy way to setup my quad monitor display using four HP USB Graphics Adapters. The result is this simple mount that attached to the pole of a quad display monitor mount (model: LCD4802Q-Stand).

While I was at it, decided to remix the basic design to attach a electrical power box so I could easily access my laptop power adapter (and other test equipment).

Very happy with the result. Simple, neat, and very functional. Moving between portable and desktop computing has never been so painl
