thermoelectric generator 3d model

3D printable model of a thermoelectric generator for student engineering project. STL format. Dimensions: 90x90x70mm casing. Components: - Two TEC1-12706 Peltier modules (40x40mm each) inside - Copper cold plate (3mm) above modules - Aluminum hot plate (5mm) at bottom - Aluminum finned heatsink (60x60x30mm) on top - 80mm cooling fan above heatsink - Four corner screws with springs for clamp pressure - Red and black wire channels - Ventilation slots on sides Requirements for 3D printing: - Manifold, watertight geometry - Minimal or no supports needed - Wall thickness at least 2mm - Clearance gaps 0.4mm for moving parts - STL format ready for slicing Visual style: Technical, clean, semi-transparent casing to show internals. Purpose: Academic project on thermoelectric generators and methods to improve efficiency (delta-T, cascading, heat isolation). Make it printable and educational.
