Multistable oloid paired half shell sampling.

The oloid and sphericon shapes are known for contacting their entire surface against a plane during a complete rolling cycle. These are an intermediate variant designed to have multiple stable positions and can be used as game die if the faces are labelled and face resting probabilities are allowed for.

I've created halfshells for printing in ABS, I suggest two perimeter walls, no bottom layer and 3 top layers, no fill. The 5 lobed variant can only fit one way, for every variant the correct way of assembly is to cross the top and bottom hard curved edge relative to each other, press together and glue with acetone or acetone/ABS glue.
