Every math teacher knows the experiment: The studends roll a normal dice over and over again and will find, that each side has the same probability of ~1/6.

But what if you roll this loaded 40mm x 40mm  40mm dice? Its inner is filled in the model, so make sure to print with 80% infill or higher.

How will the loading change the results? Would be glad to see some statistics here as a make :)

I would print in white and if you want print some black dots 0.5mm x 6mm to fill the gaps.
