spiky ball 3d model

Create a separate 3D ‘coral hat’ that fits exactly over my shell’s outer wall based on the following section dimensions: • Top horizontal segments: 30 mm + 30 mm (total 49 mm) • Outer wall thickness reference: 2 mm • Upper angled section: 30° • Lower angled section: 70° • Vertical side height: 35 mm • Lower base thickness reference: 2 mm • Entire profile is symmetrical. This new model should be a shell-shaped outer skin with an interior cavity that precisely follows these dimensions. The interior must perfectly match the surfaces above without modifying them, so it slides on like a cap. On the outside of this hat, generate realistic pillar coral formations like the reference image: — vertical, finger-like coral towers — rounded tapered tops — dense micro-texture — natural organic variation — pillars growing outward from the surface The bottom of the coral hat must be cleanly cut and open, so it can sit on top of the actual shell. Do NOT change any of the mechanical envelope dimensions of the inner mating
