A dice tower is a small construction used to roll dice for games and keep them from flying everywhere. It's a small tower with shelves (or bafflers) built in at various angles to tumble the dice in order to achieve a random result ,and drawer to catch the dice at the bottom.
I decided to laser cut one out of 1/8" wood and etch a Tiki-style face onto the front because I thought the sliding drawer looked like a big square jaw!
It's very simple to put together with the appropriate glue, as I hope the photos illustrate. I made it at TechShop!
