I made this tower to be purely functional, relatively compact, sturdy, and easy to print.  I printed mine without supports and it turned out great.  

With 15% infill and otherwise default settings in Cura it took 10 hours and about 750 grams of Overture PLA Professional filament to print on my Ender 3 Pro, so it is not the most efficient, but I plan in sending metal dice through it.  

After testing, I will update and look into any necessary improvements.

But let's be honest, it's a block, lol.
