A smaller version of my Dice organizer and rolling tray that looks like a book when closed. Holds 14 standard sized dice. 12 3mm diameter 1mm depth magnets and a pin for the hinge are required for assembly. The magnets that I have in mind can be found through this link (http://www.ebay.com/itm/252648550997), but anything similar would work and the magnets are only necessary if you really don't want the box to open accidentally. I don't have any particular pin in mind, but the hole is diameter 1/10" and runs the whole length, so just get creative about what to put in there. So long as you either have one pin that runs the whole length or two which are at least more than 3-1/4" in length (one in either end) would give a secure hinge for the lid. A slightly loose fit (but not sloppy) would probably work for best movement. Approximately 8 inches by 5 inches by 2 inches total size.

If anyone prints this, please feel free to post it with pictures and a review of how it worked out.
