Uncoupling tool holder

I have been asked a few times how I made the uncoupling tool holder. It is made out 1/2" PVC tube 3 1/2" long. My picks are 4 1/2" to 5 1/2" long. On the bottom I cut out and glued on a piece of styrene. Once that was dry I filed it down to the edge of the tube. I  then took the tubes and the 1/2" pipe holders  out to the garage and painted them gloss black. Once they were dry I installed them throughout the layout where switching takes place. They will  hold about 10 picks each. When I am taking photos I pull the picks so they do not get in the way of the shots.
