This is a variation of my Wooden DND Box.  It all slides together into one compact unit.  The Dice Tower and the Trackers slide out and there are holes for 4mm x 2mm magnets to keep them locked when storing/transporting.  

I printed the one pictured at 0.15mm Layer height, but I have also printed one at 0.2mm layer height that fit together perfectly fine.

Overall dimensions are 168mm x 116mm x 33mm

Dice Box: Has compartments for Dice, MiniFigs, Pegs, and a Dice Tray (small)

Assembly Instructions:

• Pretty easy to assemble.  Slide the pieces together.  Slides may be a little tough to slide together at first, just slide them in and out as much as needed until they slide in and out smoothly.  
• For the magnets you may need to get a 4mm drill bit (or a knife if you are brave) to make sure the holes are 4mm wide, but I have not had to do this much - usually they just push into place using plyers - the big trick will be aligning the magnets correctly so they grab each other.
