I really thought I had that part licked(vaped). It has little slots to hold my carto's (ring holders) compartments for other components(necklace and make-up spaces) A light(to see my lab experiments), a seat(for comfort, because every mad scientist needs comfort), and a mirror(to witness my clouds)! LOL, now just need it to come with usb ports and I'm set!
they sell a usb port that plugs into the wall and can attach under a conventional desk would probably work for you they can be found in office supply stores usually
