Project Title: Simple 3D CAD Model + Basic Simulation (FreeCAD) – Passive Cooling Radiator Project Description: I need a freelancer to create a simple 3D model and basic motion simulation for a mechanical engineering project. The project is based on a passive cooling radiator with adjustable fins (bimetal strip concept). The goal is NOT a complex CFD or thermal simulation, but a simple visual/mechanical demonstration. Scope of Work: 1. Create a 3D CAD model in FreeCAD (preferred): * Base/frame * Multiple fins (like blinds) * Pivot mechanism for fins 2. Create a basic motion simulation/animation: * Fins should rotate/open and close (like window blinds) * Show 2 positions: * Closed (low temperature) * Open (high temperature) 3. Export deliverables: * FreeCAD source file (.FCStd) * STEP or STL file * Short animation/video (MP4 or GIF) * 2–3 rendered images (open & closed positions) Important Notes: * No advanced CFD or thermal simulation required * Keep design simple and suitable for academic presentation * Mechanism should look realistic but does not need complex physics Deadline: * Initial preview required by 17th (for presentation) * Final delivery within 7–8 days Skills Required: * FreeCAD / SolidWorks / Fusion 360 * Basic mechanical design * CAD animation Preferred: * Experience with academic or mechanical engineering projects
