Bracket for Pez Tiered Grandstand Shelf Display

I have an ever-growing Pez collection that I like to display on my wall. I've been using grandstand style display shelves that I bought online, but the company that made them has gone out of business, so I decided to make my own. (The top left shelf in the picture is the one I made, the others are store bought.)I designed and 3D printed tiered shelf brackets and used 2"x24" pieces of Lexan (plexiglass) for the shelves. I used 3 brackets to hold up the 24" wide shelf, adjust as necessary for your particuar application.Pez dispensers are top heavy and don't really stay standing up very long, so my original plan was to string elastic thread though the holes in the brackets and over the plexiglass to help hold my Pez in place. Unfortunately, there was too much play in the elastic when run along the 24" shelves so I attached Pez Econo Display Rails (sold in 24" lengths online, PCN Store has cheapest shipping that I found) to the plexiglass instead.
