I copy pasted an oloid to Geomagic Design, stitched it, and exported to .bip, for keyshot3 (/4).


I would try to do a "gomboc," but there apparently isn't any parametric equation.
One link said it was "Constructive Solid Geometry."
Did locate an .stl reduced version.
There is a US design patent granted April 20, 2010, which lasts for 14 years.
