decorative hollow sphere 3d model

Design a 3D-printable hollow sphere 80 mm in diameter made from two threaded halves. The sphere should contain a decorative pattern of small holes evenly distributed across the surface for appearance and drainage only. Include internal reinforcing ribs, smooth exterior surfaces, and a removable screw cap for access. The model should be optimized for FDM printing, require minimal supports, and be suitable as a decorative object, toy, or storage capsule. The design must not be airtight, pressure-retaining, or intended to eject liquids, gases, or other materials.
