Regal jumping spider fidget

A print-in-place fidget toy modeled after a regal jumping spider with articulated legs and a detailed body. The design features 8 legs with 3 movable links each, hinged with 2 mm vertical pins, plus a raised cephalothorax, oval abdomen, and realistic eye arrangement (2 large forward eyes plus 6 smaller pairs). Adjustable parameters control the front eye size (1.5–5 mm radius), abdomen length (8–24 mm half-length), and overall leg reach (0.5–1.6× scale), allowing customization of proportions while maintaining the spider's distinctive appearance.
