Stackable Dice Tray With rolling Tray

See original here https://www.printables.com/model/902825-stackable-dice-tray

Basically, just matches with the dice holders but acts as a rolling tray with a flat surface. Haven't finished printing it yet but will add more pictures later. 
The purple is a thin layer of resin I added because the print failed partway through and I had to glue two halves together to make it work. Resin hid some issues with the floor of the tray plus it looks cool

Edited the model to include a rolling tray. Might make a way to link them together eventually too. But for now a rubber band it is.
