TestCube-Dice / Calibration Cube

Just thought it would be nice to print something useful as a calibration test. So I designed this little (20x20x20)mm dice. If you remember how you aligned it for printing you can use it like the other xyz-calibration cubes. ;)

Update (10-12-2019): For those of you who asked themselfes (like me) how even the dice is: I added a picture with the coordinates of the model's center of gravity. The center of the dice itself is [0;0;0] (center of gravity is [0,016; 0,081; 0,048]mm). So far for the model... Everything else depends on how you print it.
