green circuit board 3d model

Generate a high-precision CAD-grade monolithic model for 3D printing. The PCB board, electronic components, and base must be fused as one single object. No visible separation lines, no floating elements, no inset gaps, no tolerances — a watertight solid mesh. Model specifications: – Total combined thickness: 1.8 mm (PCB + components + base fully merged) – PCB, IC chips, SMD components, and traces should appear embossed, but seamlessly part of the same body. – No extruded parts should detach or float. All surfaces must be fully connected. – Underside must be flat and printable without support. – Output must be a single manifold STL-ready solid, non-hollow, non-separated. Design style: – Simplified electronics geometry (no real internal circuitry required) – Smooth curvature transitions, fillet edges where components join base – Final result must be one watertight unified mesh object.
