A dice holder and tray for Dungeons and Dragons. Holds 14 dice. To assemble, glue magnets into the slots in the lid, base, and dice cover. A pin of some sort needs to be inserted into the hinge. Approximately 12-1/4 inches by 8-1/2 inches by 2-1/2 inches in size, but the sizing for the dice was generous so you may be able to scale down the entire organizer. The design was made so as to have a flush fit in Solidwords, so finishing work may be necessary for proper fit to occur after printing.
