3D render of the Dice Tower: a graphite castle tower with a crenellated crown and corner turrets, standing in an orange tray with dice in front of the arched gate
Free 3D model

Dice Tower

Drop your dice into the crown and they bounce off two baffles, roll down the exit ramp and come out through the arched gate into the tray. The baffles overlap, so nothing falls straight through, and there is at least 31 mm of room everywhere inside, so d6, d20 and every die in between roll freely. The tower is two halves that print lying down; the crown slides over the top and the tray's collar holds the bottom, so it needs no glue and comes apart for storage.

Tray

The dice land here: 110 × 150 mm with an 18 mm rim and a 1.2 mm recess in the floor for a felt sheet. The collar at the back holds the foot of the tower with 0.3 mm play.

Also needed

Parts you buy

  • 6 pieces of 1.75 mm filament, 10 mm long, as alignment pins between the two halves.
  • Optional: a self-adhesive felt sheet, 1 mm thick, cut to 100 × 64 mm with rounded corners, for the tray. It makes the dice quieter.
  • Fits dice up to about 25 mm across, so a standard d20 and 16 mm d6 roll through easily.

Assembly

How to build it

Print the parts

Print the two halves lying on their outer side wall, the crown upright and the tray flat. None of them needs supports. Turn on elephant's foot compensation, or scrape the bottom edges of the halves, so the tower drops into the collar easily.

Fit the pins

Push a 10 mm piece of filament into each of the six holes in the cut edge of one half. If a pin is loose, put a drop of glue on it.

Join the halves

Press the other half onto the pins until the cut faces meet all along the tower.

Put on the crown

Hold the halves together and slide the crown down over the top until it stops.

Stand it in the tray

If you use felt, stick it into the recess first. Then lower the tower into the collar at the back of the tray, gate to the front.

Roll

Drop your dice into the crown. They come out of the gate into the tray.

Dice and the filament pins are small enough to swallow: keep them away from small children.
