[ 1 week ]3D Product Designer / Mechanical Engineer for Prototype

Project Overview: We are looking for an experienced 3D CAD designer or mechanical engineer to reverse-engineer and design a functional, 3D-printable prototype of an autonomous driving sensor housing (roof pod). The housing is intended to be mounted on a Hyundai Ioniq 5. Concept & Visual Reference: We will provide a highly detailed 2D concept cutaway diagram (see attached file) to guide the internal layout and external aesthetics. Key Requirements & Scope of Work: - Engineering for 3D Printing (Solid Modeling): This project requires precise parametric CAD modeling (e.g., Fusion 360, SolidWorks, CATIA), NOT just a polygon mesh for visual rendering. The model must be structurally sound and optimized for physical prototyping (SLA/FDM 3D printing). - Internal Hollowing & Mounting: The shell must be hollowed out to accommodate internal wiring harnesses, an edge computing unit, and precise mounting brackets. - Sensor Integration & FOV Clearance: You must design exact mounting points ensuring clear Fields of View (FOV) for the following components: - 1x Velodyne Alpha Prime 128-channel LiDAR (Center top) - 2x Forward-facing cameras - 4x Side-facing cameras (2 left, 2 right) - 1x Rear-facing camera - Part Splitting & Assembly: Because the pod is large (spanning an SUV roof), the final CAD model must be logically split into modular, interlocking pieces suitable for standard large-format 3D printers. The design must include mechanisms for assembly (e.g., holes for threaded heat-set inserts, bolts, or snap-fits). - Roof Curvature Matching: The base of the pod needs to be shaped to accommodate the general roof curvature of a Hyundai Ioniq 5 and include mounting points for a roof rack/crossbars. Deliverables: - Source 3D files - Universal solid CAD models (.STEP and .IGES) - Print-ready mesh files (.STL or .3MF) properly oriented for the split parts. - A brief visual render showing the assembled parts.
