Adjustable probabilities of faces

[tureba]

Would be interesting if it were possible to generate the dice with adjustable probabilities of faces.

I was thinking that a d16 could have numbers 3 through 18, and the same probabilities for those numbers as rolling 3d6. Or maybe a d11 with the same numbers and probabilities as 2d6, to surprise Catan games with a novelty dice. Or anything else along the same lines.

It might be achieved either by sizing the face areas proportionally to the intended probabilities, or by putting carefully-chosen holes on the inside of each face, instead of a solid infill. I don't think these are easy to do in the slicer, though.

Thoughts?
