It's a simple 14mm^3 dice. Write whatever you want on the sides and use it for whatever you want. Write 1-6 to use as a regular dice, or dares, or nothing. Use it for games or fidgeting. It can be anything. 

I printed it in 100% infill for a bit of weight. You can make it less dense, or bigger/smaller. 

Again, it can be anything you want it to be.
