mecha robot 3d model

Generate a 3D-printable foldable robot based on the black armored monster-mech in the reference image. The robot must transform between two forms: a humanoid armored mech mode, and a compact cube mode. Match the character style from the reference: thick mechanical armor plates, robust limbs, segmented plating, smooth panel lines, and glowing eyes. Avoid fragile spikes—convert small spikes into thicker, rounded nubs suitable for printing. Design the robot with simple, sturdy folding mechanisms that work for FDM printing: block hinges, rotating pins, or sliding panels. Ensure all joints have at least 0.3 mm clearance and can be printed without supports. Keep geometry chunky and toy-like, with no thin walls or tiny projections. Output Requirements: – Output only a clean, watertight 3D mesh suitable for export as STL or OBJ. – No text description; return only the generated 3D model. – The final geometry must be a single unified model containing all robot parts and folding joints. – Surfaces must be manifold,
