I need simple 3D CAD model of a gear / sprocket. i intend to submit the design to a prototype manufacturer who requires a CAD file as a first draft. We intend to use several material types. It is actually closer to a shell or skin of the gear/sprocket and not the actual gear itself… (Budget: $30-$250 USD, Jobs: 3D Rendering, AutoCAD, CAD/CAM, Manufacturing Design, Mechanical Engineering)
