This combination dice box and tower is a perfect display/storage box and automatic dice roller designed for standard-sized dice. It's built from readily-available 1/8" material, and is perfect for your standard (19mm d20) dice sets. It is designed to travel with dice inside, and also contains a "basement" storage area good for extra dice sets, figurines, counters, or whatever else you'd like to store.
Dan at Glowforge evolved the design to include serrated tabs, which can be hammered together to fit without glue. See his forum thread for the download.
Finished size: 3"x3"x6"
