Fractal cube known as Menger's Sponge (or 3D Sierpinski's carpet).
This shape has infinite area and zero volume - it means very hard to calculate (time/memory) in higher order, and hard to 3D print-out.
I could calculate up to 4th order using PC and 3rd order using cheap FDM printer. Expecting anybody challenge more!!
