organic cube 3d model

Create a 3D printable organic cube with a smooth, continuous surface. The structure should NOT be uniform or random. Instead, it should have a clear directional flow, as if the geometry is being pulled or stretched from one side. The internal voids should behave like a Voronoi or cellular structure, but with variation: * larger elongated openings along one axis * smaller, denser pores in other regions Avoid evenly distributed holes. The geometry should feel like a network of flowing channels or veins, not a sponge. The cube should maintain an overall cubic boundary, but with soft deformation and curvature. Style: * biomorphic, bone-like, or vascular * smooth transitions (metaball / implicit surface) * directional asymmetry Constraints: * watertight mesh * minimum wall thickness 2–3 mm * suitable for 3D printing Important: The form should emphasize directional stretching and flow, not random noise-based perforation.
