www,celalettintoprak,com I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m an Engineer and Industrial Product Designer focused on manufacturing-driven product development. My background spans automotive, industrial, and consumer products, where I’ve worked as a Product Developer, Designer, and Technical Lead in production-oriented environments. I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.

Industrial Designer & Sheet Metal Shop Owner | Production-Ready CAD & Machinery Solutions Hello! I am an Industrial Designer with extensive hands-on experience in sheet metal fabrication and machinery manufacturing. As a business owner in the manufacturing sector, I don’t just create pretty 3D renders—I design products that can actually be built efficiently and cost-effectively. Most design issues happen on the shop floor: wrong bend deductions, impossible weld joints, or high material scrap. Because I run manufacturing operations myself, I anticipate these problems during the initial CAD phase. What I Bring to Your Project: 100% Production-Ready Files (DFM): Accurate 3D models and 2D DXF/DWG flat patterns (unfolds) with precise bend allowances (K-factor). Machinery & Enclosure Design: Custom machine frames, sheet metal covers, panels, and industrial equipment. Cost & Assembly Optimization: Reducing part counts, minimizing laser cut waste, and simplifying assembly to save you time and money. Complete Manufacturing Packages: Step/Iges files, exploded assembly views, and detailed Bills of Materials (BOM). Whether you need a product designed from scratch or existing CAD files fixed for manufacturing, I am here to help. Let’s discuss your project and turn your ideas into shop-floor reality!

Industrial-Grade PCB Layout, Hardware Prototyping & DFM Optimization Services I provide full-cycle electronics engineering, schematic translation, and manufacturing-optimized PCB layout services. Utilizing industry-standard design disciplines (with native proficiency in KiCad), I specialize in transforming conceptual circuit designs into stable, high-performance physical hardware. My expertise spans custom microcontroller expansion shields (Arduino Mega/ESP32 formats), multi-channel sensor integration arrays, bi-directional logic level-shifting networks, and localized decoupling architectures. My design methodology prioritizes advanced Design for Manufacturing (DFM) principles to completely mitigate automated SMT assembly risks—such as component tombstoning—by implementing symmetrical center-trace entries on passives. Furthermore, my layouts emphasize signal integrity through unbroken ground return plane topologies to drastically minimize loop inductance and eliminate electromagnetic interference (EMI). Every project undergoes a meticulous Design Rules Check (DRC) to ensure a 100% zero-defect rate before final handoff.

I am a mechanical engineer and product design specialist with over three years of experience turning ideas, sketches and reference photos into CAD models that can actually be manufactured, not just rendered. WHAT I DO - Product design and 3D CAD modelling in Fusion 360, SolidWorks and AutoCAD - Design for Manufacturing (DFM) reviews before tooling: draft angles, wall thickness, undercuts and features that drive up production cost - Injection-moulded parts, machined parts and sheet metal design - Print-ready STL and 3MF files for FDM and SLA, checked watertight and manifold after export, with tested 0.3–0.5 mm fits so parts assemble first time - Reverse engineering from sketches, photos, PDFs and legacy drawings into clean, editable parametric models - Dimensioned technical drawings with tolerances and GD&T callouts, assembly drawings and bills of materials - CNC programming, nesting and MPR file generation - Photorealistic renders in Blender for pitch decks, listings and investors HOW I WORK Every model is built as a parametric master with a clean feature tree, so a new size or variant is a parameter change, not a full remodel. Before I start, I tell you honestly if a feature will be hard or expensive to manufacture, so problems are caught on screen rather than at the quote stage. RECENT PROJECTS - CAD optimisation and structural verification of a packaging insert with complex internal cavities, including finite element validation (SolidWorks) - Redesign of a gas-driven piston accumulator for manufacturability (SolidWorks) - Consumer product delivered in two production-optimised variants with full 3D data and 2D drawings - CNC nesting and custom MPR file generation for production machining - 3D printable lamp shade and base, validated for FDM production WHAT YOU RECEIVE Native source files, STEP, STL/3MF, DXF and PDF drawings, plus a BOM where needed

I am a mechanical engineer with 3+ years of hands-on CAD and product design work, combined with a strong software background. That mix lets me cover the full journey: designing the product, visualising it, documenting it, and automating the repetitive CAD work around it. WHAT I DO - Product design and 3D CAD in Fusion 360 and SolidWorks: enclosures, housings, consumer products and functional parts, designed for 3D printing, injection moulding and CNC - Photorealistic 3D rendering and visualisation in Blender: product shots, jewellery and accessories, lifestyle scenes and marketing visuals for websites, listings and investor decks - Revit BIM modelling: CAD to BIM conversion, architectural and MEP models, and drawing sets - CAD automation with Python: scripted, parametric CAD (OpenCASCADE), batch export and file conversion, model checks and custom tools that save hours of manual work - Reverse engineering from photos, sketches and drawings into clean, editable models - 3D printing preparation and prototyping on in-house FDM printers HOW I WORK I build models parametrically, so changes are quick and variants are easy. I check designs for manufacturability before delivery, and I tell you early if something will be expensive or difficult to produce. Where a task repeats, I automate it, so you pay for engineering rather than clicking. RECENT WORK - Two-part wall-mounted electronics enclosure (ABS body + polycarbonate cover with vent slots), built with scripted parametric CAD and delivered as clean STEP files - Rugged hinged protective case with toggle latch, recessed handle and stacking interlock, designed print-ready for FDM - Photoreal product visualisation for decorative hardware and jewellery collections - Reverse engineering of complex shapes from reference photos into dimensioned CAD WHAT YOU RECEIVE Native CAD files, STEP, STL/3MF, DWG/DXF and PDF drawings, Revit files, high-resolution renders, and scripts with simple instructions where automation is part of the job.

I help businesses, startups, and inventors transform product ideas into functional, manufacturable designs using SolidWorks. My expertise includes 3D CAD modeling, mechanical product design, prototype development, and Design for Manufacturing (DFM). I focus on creating accurate, production-ready models with attention to functionality, assembly, tolerances, and ease of manufacturing. Whether you need a concept developed from scratch, an existing design improved, or files prepared for 3D printing or injection molding, I deliver clean, organized, and editable CAD models. I can provide native SolidWorks files, STEP, STL, and technical drawings & solutions that help move products from concept to prototype and ultimately into production. Send me a message with your sketch or requirements today to discuss how we can bring your idea to production!
