Hello, I’m Mina, a Mechatronics Engineer and product designer. This is the type of project I enjoy working on because it combines consumer product design with real manufacturing requirements. Based on your description, I understand that this is not just a visual model—the design needs to be ready for rotomolding, concrete filling, and commercial production. I can develop the CAD model following the attached rendering while incorporating the necessary manufacturing considerations, including draft angles, wall thickness recommendations, hidden parting lines, internal reinforcement features, and a concrete cavity that provides stable weight distribution. My focus would be on maintaining the premium appearance shown in the rendering while ensuring the part is practical to manufacture and durable for long-term outdoor use. Deliverables can include: • Production-ready CAD model • STEP file • Native SolidWorks/Fusion 360 files • Dimensioned drawings • Exploded assembly view • Manufacturing and DFM recommendations A couple of questions: • Do you already have a preferred rotomolding supplier, or should the design follow general industry guidelines? • Will the concrete be poured after shell assembly, or are you considering molding around a pre-cast insert? You can review my previous work and client feedback on my profile. I look forward to discussing the project. Best regards, Mina
