The CuBE - Menger Fractal Dice Tower

I was playing around with cubes in my CAD software when I had an idea. Turns out part of that idea had a name: the Menger Sponge (…what?…) This 3D cubic fractal serves as the centerpiece for my new dice tower.

There are two different versions, a standard one, and a detailed one (the detailed one has way more holes in it.) Each of these also has a solidified version where most of the small holes are plugged up, but still visible as a surface detail. These “solid” variants also take much less time and material to print than their holier counterparts (there's a joke in here somewhere…)

The largest holes are 30mm x 30mm, which is enough for any standard dice to roll through with ease. There are three entry holes in the top, with two exit holes leading into a single tray at the bottom. The inside surfaces are sealed such that unruly caltrops don't get their points caught in any holes.

Feel free to scale these to suit your needs, just make sure your dice can still roll down without getting stuck. Let me know if you have any questions or comments, and happy printing!
