weathered rock 3d model

An organic porous stone inspired by weathered limestone and lava rock, designed as a single solid volume suitable for 3D printing. The stone has a tall, irregular pointed peak at the top, with fractured, jagged ridges and vertical erosion channels. The base is wider, smoother, and gently rounded, forming a stable footprint with fewer sharp edges, as if worn by water. Surface texture is highly uneven and natural, with cavities, pockets, and layered rock faces, but no thin spikes or fragile overhangs. The form should feel heavy, geological, and naturally eroded, not symmetrical or artificial. No flat planes, no geometric patterns, no man-made shapes. Neutral earthy tones implied (brown, tan, gray, mossy hints), but geometry only. The model must be watertight, manifold, and printable as a solid mesh, with sufficient thickness everywhere and no internal hollow chambers. 3d printer, rough shape
