36 d6s for random counters or rolling for MTG. Each dice has an MTG logo.
If you want a different logo, check the model that was remixed and add a logo to that and print those instead, MAKE SURE they are 12mm!
 

Includes a box to hold 36 of the dice.

Each dice is 12mm in diameter.

Print Settings
I recommend printing the dice with brim enabled. Unless you have really good bed adhesion, they will fly off. The brim is easy to take off and doesn't leave too much of a mess.
Also print with 100% infill on everything, including the box. This makes the dice fair and nice to hold, and the box will be much stronger.
For more detail on the dice, decrease layer height. I recommend 0.16 or 0.12.

I modified the original model with the MTG logo and creating the box to hold the dice.
