Companion Cube Deckbox - 75 Card

This is a remix of http://www.thingiverse.com/thing:1031683.
My modifications:
-Modified the dieholder to hold 36 12mm D6.
-Edited the deck size to match a 75 card double sleeved deck
-With the extra room modified it to hold 4d20's

Note after printing
-D6 holder hole required slight sanding to glide smoothly.
