Household Prototype 3D Model Design

I have a new household item in mind and I’m ready to move from sketches to a working prototype. I need a precise 3D CAD model that can be sent straight to either a 3-D printer or a CNC shop, so the geometry must be manufacturing-ready rather than just a visual render...
