Siraj U.

Have a product idea, concept, or existing design that needs to become a functional, manufacturable product? I help startups, inventors, entrepreneurs, and brands turn ideas into production-ready products through mechanical product design, SolidWorks CAD, prototyping, DFM, and manufacturing-focused engineering. I'm a Mechanical Product Designer with 4+ years of experience developing consumer products, mechanical components, assemblies, plastic enclosures, and physical products from concept through prototyping and manufacturing preparation. My work goes beyond creating 3D models. I design with function, assembly, materials, tolerances, manufacturability, and production methods in mind—helping identify potential issues early and reduce costly revisions during prototyping and manufacturing. 🔧 What I Can Help You With Mechanical Product Design & 3D CAD • 3D CAD modeling in SolidWorks & Fusion 360 • Product development from sketches, concepts, references, or existing CAD • Mechanical parts, assemblies, and consumer products • Plastic housings, covers, enclosures, and components • Design modifications and reverse engineering • Concept development and design refinement • Design optimization for functionality and manufacturability Design for Manufacturing (DFM) • Injection molding & plastic product design • CNC machining • Sheet metal fabrication • FDM / SLA 3D printing • Draft angles, wall thickness, ribs, bosses, and other molding considerations • Parting-line and assembly considerations • Tolerances, fit, and manufacturability • Design optimization for practical and cost-effective production Prototyping & Product Development • 3D-printable prototype design • Prototype optimization • Fit and assembly validation • Design iterations based on prototype feedback • Functional prototype development • Preparing designs for manufacturing Technical Documentation • Detailed 2D manufacturing drawings • GD&T and tolerancing • Bill of Materials (BOM) • Assembly drawings and documentation • Product specifications • Manufacturing-ready CAD deliverables Rendering & Product Visualization • Photorealistic product rendering • Product presentation visuals • E-commerce product images • Concept visualization 📦 Products & Projects I Specialize In • Consumer products • Mechanical products & assemblies • Plastic products & injection-molded components • Electronic enclosures & housings • Kitchen & houseware products • Outdoor products • Home & lifestyle products • Amazon products • Industrial components & equipment • Custom mechanical mechanisms ⭐ Why Work With Me? Engineering-First Product Design I don't just create models that look good. I focus on functionality, mechanical feasibility, assembly, tolerances, and manufacturing requirements from the beginning. Manufacturing-Aware Approach Whether your product will be injection molded, CNC machined, 3D printed, or fabricated from sheet metal, I consider the manufacturing process throughout the design. Strong SolidWorks & CAD Expertise I create clean, accurate, and well-structured 3D CAD models and assemblies that are practical for prototyping, engineering review, and manufacturing. From Concept to Prototype Give me a sketch, reference image, rough idea, or existing CAD file, and I can help develop it into a detailed and functional product design. Clean & Reliable Deliverables You receive organized CAD files, accurate models, detailed drawings, and documentation structured for real-world use. Clear Communication I keep projects organized, communicate progress clearly, and focus on practical engineering solutions rather than unnecessary complexity. If you're looking for a Mechanical Product Designer who combines SolidWorks CAD, product development, DFM, and injection-molding knowledge, send me your idea, sketch, reference, or existing CAD files. Let's turn your concept into a product that can actually be built.
