This is a large dice with an elegant stand. 

The cube edge size is 30 mm (1.1 inches) . 
The height of the stand is 110 mm (4.3 inches) 

You need to select the desired color for the cube, dots and stand in the slicer. 

Note, in the pictures I made the big dot red and the rest black. You can assign them all one color or different ones of your choice.
There are 21 dots on the cube in total. Twenty small dots and one large one.

When printing, no support is required, but you will need to glue the dots into place afterwards.
I have attached a standard Bambulab profile and only changed the profile of the filling of the upper surface of the stand to concentric, since the stand is round. If you want to make it heavier, add perimeters and increase the infill.

Remember from the point of view of probability theory this is not a correct cube, because its density is not uniform and the probability of each face falling out is not the same :)
