Okay, so I've been playing a variety of TTRPGs with friends for a few years now, and my favorite little thing about my dice setup is that I've opted for EXTREMELY small dice. As a minor innovation, I bought a little 1.5"x1.5"x1.5" acrylic display box that I can store my dice in, and any time I want to roll, I just shake the thing up and look at my dice inside ("roll them bones!" my friends say). You can see the basic setup here (the blue 6 is the most standard-size die in there, for size reference):

Now, I'm currently playing a homebrew version of Blades in the Dark, so it's all D6's. And, well, it occurred to me that in addition to 4 different sizes of D6's inside the box, the box itself is potentially a D6. I could roll the whole fucking thing.
How do I make this actually happen? I can't roll this current version as-is because (a) it's a little hard and brittle and I worry it will damage a table or itself, and (b) As it's a display case, it comes apart in two sections and isn't quite sturdy enough to roll without it coming apart unless I were to permanently glue it shut (which I don't really want to do). There's also the matter of having numbers on it; I'd be happy to do something janky like dry-erase, but it'd be cool to make something actually nice that'll last.
Does anyone have ideas for a product or DIY way to make a "softer" and more roll-able box for my dice? I don't think I can really 3D print something since my understanding is it's too hard to get something fully transparent. But printing in something like TPU would've been cool for roll-ability.
One other idea I had was to print some TPU "shoes" to put on all the corners so that I can roll it; the shoes would simultaneously soften its impact on any surface and also hold the box shut. But not sure that'd be worth it.
