The prompt
Mechanical 3D CAD model of a robotic spider chassis with articulate joints, optimized for 3D printing. The model consists only of functional mechanical parts. The main body features a hollow cylindrical mounting socket or cradle on top, with an internal diameter of 91mm and a depth of 35mm, designed to tight-fit a cylindrical speaker (Yandex Alisa Lite 2) as its head. Branching out from the central chassis are 4 or 6 multi-segmented mechanical legs. Each leg must have fully functional, moveable mechanical joints: a hinge joint at the hip, a pivot joint at the knee, and a ball-joint or ball-socket at the foot for realistic articulation. Clear clearances of 0.3mm between moving joint components to ensure print-in-place or assembly functionality. Engineering-grade aesthetic, B-Rep solid geometry, no organic textures, functional mechanical linkages only.
