Dice Box With Tray

I decided to turn the one side into a dice tray, which can be lined with felt or left as is. I loved the original design, but thought "that other half of the box isn't doing much while it's open, that's prime real estate!"

I used the '3D Print with Treatstock' option to test out this build. Great quality print! I then added some magnets to the corners and felt in the bed of the rolling tray. I have a few ideas how to even further improve this design.
