I loved the secret shelf design by Tosh so much so that I wanted one for my office to keep spare change or a set of keys to my desk. Of course my office is more of a cloth jail cell than an actual office, so I needed to do a few modifications.
I removed the screw holes in the back and added hooks for my cubicle (I'm not sure if all cubicles allow for standard hooks, but I hope so). I designed this to mount on the joint where two walls meet.
Supports are required for the hooks
