Colored 6 sided die

Simple die - printable without wastetower though (sometimes)!

Each layer has sufficient amount of each color, when printing outer walls as last item it means the rest of the inner side of the die can serve as waste - if it is printed big enough and depending on how much you printer oozes or needs to purge.

You can even venture into 3 colors (body, odds and evens)

First 3color version is printable, put slicer needs to manage mesh intersections. "Die2" keeps all nicely separated. I assume printing the 4 or 3 down shall yield best results without prime tower.
