Caddy Clip – Retractable Golf Brush | Mechanical Product Design & 3D CAD Modeling

This project focuses on the conceptual mechanical design and product development of a compact retractable golf club cleaning brush called Caddy Clip. The objective is to develop a practical, durable, and portable cleaning accessory that can conveniently attach to a golf bag or belt loop. The product features a compact ergonomic handle, retractable cord mechanism, attachment clip, and interchangeable nylon-bristle brush heads. The design emphasizes functionality, ease of use, secure component connections, durability, and manufacturing feasibility. Scope of Work 1. Handle and Product Housing Design Development of a compact and ergonomic brush handle. 3D modeling of the external housing. Design considerations for comfortable grip and handling. Integration provisions for the retractable cord mechanism. Design of attachment points for the carrying clip. 2. Interchangeable Brush Head System 3D modeling of replaceable brush head components. Design of a secure connection between the handle and brush head. Development of a locking mechanism concept. Consideration of snap-fit, sliding-lock, bayonet, or quarter-turn connections. Accommodation of medium-soft and medium nylon bristles. 3. Mechanical Mechanism Development Conceptual integration of an off-the-shelf retractable reel. Retractable cord routing and housing considerations. Attachment clip integration. Evaluation of component positioning and mechanical clearances. Design considerations to prevent accidental brush-head detachment during normal use. 4. Design for Manufacturing Plastic housing and component design. Injection moulding considerations. Wall thickness and draft angle considerations. Snap-fit and locking feature design. Component separation for manufacturing. Design considerations for an initial production quantity of 500–1,000 units. Technical Design Considerations Compact and lightweight product construction. Secure interchangeable brush-head connection. Durable plastic housing design. Water, dirt, and outdoor-use considerations. Ergonomic handling and accessibility. Replaceable nylon-bristle brush heads. Compatibility considerations for retractable reel and attachment hardware. Geometry suitable for functional 3D printing and future manufacturing development. Software & CAD Tools SolidWorks – Mechanical design, 3D part modeling, and assembly development. Autodesk Fusion 360 – Product development and mechanical modeling. AutoCAD – Technical drawings and manufacturing documentation. Proposed Deliverables Native editable CAD files. STEP and STL file exports. Detailed 2D engineering drawings. Exploded assembly views. Basic Bill of Materials (BOM). Mechanical component and locking mechanism details. 3D-printable prototype files. Manufacturing considerations for future injection moulding. Project Outcome The design concept demonstrates the development of a compact mechanical consumer product with interchangeable components and integrated attachment features. It highlights my capabilities in mechanical CAD design, product modeling, assembly development, mechanical mechanism design, and design for manufacturing. Have an idea for a new consumer product or mechanical accessory? I can help transform your concept, sketches, and references into detailed 3D CAD models and professional engineering designs.
