The storage cases used on Deep Space Nine were always my favorite. These cases were used on the station, in Odo's office and the cargo bays, and onboard the Defiant, on the bridge and in the crew quarters.
Made by Rubbermaid, the "ActionPacker" cases were originally designed for storage of tools and auto supplies, small enough to fit in the trunk of a car, or you could also hang in on the wall in your garage. Unfortunately this style case is no longer made. Rubbermaid still makes ActionPackers but not of this design. Now the only place to find these cases are garage sales, flea markets or thrift stores, which is where I found this one.
I converted it to look like the one on the bridge of the Defiant during season 7. The third picture is what one looks like in it's original form.
