I've gotten into DMing D&D lately,  and I've been inspired to make a print-in-place dicebox/dice tray/device stand. 

This will print in place on a standard prusa mk3. I've also included separates in case you wanted to do some different color combinations without a MMU (or if the print in place hinges are a challenge for you) 

The latch is a slight remix of the Reliable Chest Lock (https://www.thingiverse.com/thing:3264863). 

Print your box, print a latch, and superglue it to your box once it's done printing, and you should be ready to rock.
