chainsaw man figure 3d model

"Generate a stylized chibi Chainsaw Man figure with a simplified body and exaggerated proportions. Use clean, low-poly to medium-poly geometry with smooth surfaces and minimal fine details. The chainsaw head and arms should be chunky and solid, not thin. Ensure the entire model is a single, watertight, manifold mesh with no internal geometry, no floating pieces, and no intersecting parts. Avoid tiny spikes, sharp thin teeth, or complex mechanical details. Keep the forms rounded and easy to unfold in Pepakura. Output as one closed, solid mesh suitable for papercraft."
