3d Cad Design for Drybag Accessory Rail and Interlocking Key System

We are seeking a skilled CAD designer to translate a conceptual design for a drybag accessory system into detailed 3D CAD models. The system consists of a primary rail and interlocking keys designed to securely attach various accessories to a drybag. We currently have the rail and key designs documented on paper, including dimensions and functional principles. The successful freelancer will be responsible for creating precise CAD models of these components, ensuring all interlocking mechanisms are accurately represented and functional. Deliverables will include native CAD files (e.g., SolidWorks, Fusion 360) and potentially rendered images for visualization. Experience with mechanical design and precision engineering is highly valued.
