DD Stile dice case

A small clamp-box for keep my D&D dices. It's designed in sketchup using part of the "D&D dice case by MTD7" and the basic idea of the "clamp box by RoboBaggins" I'd like to add a better finish to the box, adding a rock texture, but sadly I dont have a better program like Fusion360 and I dont know how to use better program like blender.

Edit: I added an empty bottom case (without dice forms) for use with more dices or other things
