This is D-prime minimal surface with t=0,3 because only in small interval of t this type of surfase is printable and this t value is about optimal.

There are two complimentary volumes made by division of a single solid cube with D-prime surface. They are not identical like those made with Diamond, Gyroid or some other surfaces, that give two similar or identical (t=0) volumes mirrored by axonometric(?) plane.

This is a part of minimal surface crappy mesh catalogue.
