The original model was too large to fit in your pocket or dice bag easily.  I shrank it down, and added print in place hinges to make this all stay together in one piece. I also added Ampers to the Front and back as well as rounding out some sharp corners.  I just took this to Dungeon Con and it worked great. 

Printed with a .4 nozzle .2 layer height.  Auto Tree supports Slim were able to get in place with minimal effort. No assembly necessary.  The tolerances between the two pieces are really tight.  I used the bambu scraper blade to carefully separate and then pivot the pieces at the hinge.
