A dice tower makes every roll fair: you drop the dice in the top and they tumble out at the bottom, so nobody can ‘place’ a roll. For a DnD table it’s also a centerpiece, and 3D printing is how most of the detailed ones are made. Here are nine dice tower ideas from Etsy shops.
Fantasy Dice Towers
Fairy Dice Tower

A tree house with mushrooms, made for DnD 5e, Pathfinder and other tabletop RPGs. It comes paint-ready so you can color it yourself.

Sunken Pirate Ship Dice Tower

The wreck of a ship with its helm still standing, from the same shop, for a pirate campaign.

Painted or Raw?
Several towers here come ‘paint-ready’, meaning printed in one color for you to paint. That’s half the fun for many DnD players, and it lets the tower match your campaign. If you want it ready to use, look for a painted option or a multicolor print like the storage box.
