I want to build some shelves to store trays of dice. The trays are 13.7" x 8.6" x 1.37" and are ~4.5 lbs when completely filled with dice. I want to pull the shelves out far enough to open the tray, but not come all of the way out of the storage box.
I put some dowels on my design as that is what I would try first, but I have no idea if this will work in practice or how long they will last. What's the best (inexpensive) option to stop the shelves from coming out completely?
Here's my design as I would try to build it today: https://www.tinkercad.com/things/jsiPei6bP1y-dice-tray-storage
