Most hardware products die in the gaps where a handoff occurs. You hire a designer, then an engineering firm, then a tooling vendor, then a factory. Months disappear into translating between them, and the money goes with it. I have watched it happen to good founders with good ideas. I spent 13 years in product design and engineering, seven of them at Dyson, taking complex consumer products from concept to production. I saw the same thing at Ruroc and with founders coming to Gembah for help when I worked there. Founders losing momentum, not because the idea was wrong, but because the process was fragmented. So I built Enki Product Development to close the gaps. One unified team of ex Dyson engineers, taking ambitious consumer brands from idea to shelf. No handoffs. No translation losses. No moments where your product falls between the cracks. Around 90% of our engineers came from Dyson, with over 100 combined years of experience there. They have led product categories, developed entire ranges and delivered complex products at scale. The people who shape your concept are the same people who engineer it, design it for manufacture and place it with the factory. We spot the expensive mistakes before they happen, not after the steel is cut. Five stages, one roof: 1. Discover: market, design and technology research leading to a product definition 2. Define: concept sketches, models and working prototypes 3. Design: engineering it to actually work 4. Develop: design for manufacture and cost engineering 5. Deliver: factory selection and supply chain 80+ products to date, for clients including HexClad, Rorra, Airbotx and AromaTech. Categories: home and kitchen appliances, consumer electronics, wellness, baby products and personal care devices. Chartered Engineer (CEng MIMechE). BSc Product Design, 1st Class Hons, Nottingham Trent University. What our clients say: "Working with Ben and the rest of the Enki Product Team on the development of the Filtered Pitcher was a great experience. Enki has a rare combination of full-stack, integrated engineering and design which was extremely useful throughout the entire development process and saved us both time and money for getting new products to market. They helped us stay on top of major milestones and treated the product as their own. We've engaged with Enki for additional projects as well, which supports our trust in their team."

When I am studying at 10th std, I sighted crane which is lifting an large block of stone in the adjacent street of my school. A thought came how crane bearing the stone block. I loved to watched to sight that scene. But I don't think of any science in that scene. But when I am reaching my final year of engineering, I tried to learn to learn about the science. Then I thought of how it is created. Then I learned about the design and started to use the software autocad and solidworks. My interest level gone up when using these software. I designed my own project using the Solidworks. The cadcrowd gives me the oppurtunity to show my talent. Thank you for reading.

PRODUCT DESIGN AND PARAMETRIC CAD: FROM AN IDEA TO FILES A MANUFACTURER CAN USE I'm Collins, a product designer and CAD modeler based in Lagos, Nigeria (GMT+1). I turn ideas, sketches, photos, measurements and rough CAD into files that a factory, machine shop, fabricator or print shop can quote and build from: 3D models, 2D manufacturing drawings, flat patterns, cut lists and presentation renders. This page is long on purpose. It tells you exactly what I design, what you receive, how a project runs and what I do not do, so you can decide quickly whether I am the right person for your job. WHAT I DESIGN Every area below has a worked example in my portfolio, with the drawing and the 3D files attached, so you can judge the quality before you message me. Plastic products and enclosures - Injection-molded parts and housings: draft angles, uniform walls, ribs, bosses, snap fits, hinges, latches and seal grooves - Electronics and IoT enclosures built around your circuit board, connectors and battery - Sealed housings with gasket or O-ring grooves, cable glands and mounting features - Wearable and handheld device cases Portfolio examples: hinged storage case, IoT sensor enclosure, sealed die-cast enclosure, wearable sensor housing Consumer products and mechanisms - Products designed to be 3D printed first and molded later - Hinges, twist locks, bayonet fittings, snap hooks, clips and quick-release parts Portfolio examples: adjustable phone stand, twist-lock brush handle, stainless snap hook Machined, sheet metal and extruded parts - CNC parts with toleranced drawings: fits, threads, counterbores and finish callouts - Sheet metal parts with flat patterns, bend lines and bend deductions - Aluminium and plastic extrusion profiles with section data - Brackets, mounts, clamps, jigs and fixtures Portfolio examples: tube clamp block, sheet metal chassis, LED channel extrusion, NEMA 17 motor mount Gears, tooling and machines - Involute spur and planetary gear sets generated from the gear data - Injection mold core and cavity inserts with runner, gates, ejection and cooling layout - Machine concepts and general arrangement drawings Portfolio examples: 4:1 planetary gearbox, two-cavity mold inserts, dual-shaft shredder Fabrication and process equipment - Welded frames and structures with cut lists - Ladders, platforms and steelwork drawn for fabrication - Tanks and vessels as general arrangements with nozzle schedules - Pipe spools with bills of materials Portfolio examples: trailer chassis, caged access ladder, pressure vessel, flanged pipe spool Wood and laser-cut products - Cabinets and panel furniture nested for CNC routers, with cut lists - Laser-cut plywood and acrylic products with finger joints and cut sheets Portfolio examples: flat-pack base cabinet, plywood desk organizer WHAT YOU RECEIVE - STEP files of every part and of the full assembly. STEP is the neutral CAD format: it opens in SolidWorks, Fusion 360, Inventor, Creo, Onshape, FreeCAD and whatever software your manufacturer uses - STL or 3MF files for 3D printing, where the part is printed - A dimensioned 2D drawing as PDF and DXF: views, section and detail views where they are needed, tolerances on the dimensions that matter, material, finish and notes - Flat patterns, nests and cut sheets as 1:1 DXF for laser, router or plasma cutting - Tables where they help: bill of materials, cut list, gear data, nozzle schedule - Part volume and weight, and a fit check of the assembly - Presentation renders and labelled boards you can show to investors, customers or your own team HOW A PROJECT RUNS 1. Brief. You send what you have: a sketch, photos, measurements from a sample, a STEP file, a data sheet or just a description. I reply with questions, not guesses. 2. Quote. A fixed price per milestone, or an hourly rate for open-ended work, with a delivery date for each milestone. 3. First model. You see views and renders of the design before any drawing is made, while changes are still cheap. 4. Checks. I check assemblies in 3D for parts that overlap or collide, move hinges, latches and gates through their travel, and work out the numbers that decide whether a detail will function: snap-fit strain, seal squeeze, bend allowance, clearances and weight. 5. Drawings and files. The drawing set and every file listed above. 6. Revisions. Every model is parametric, which means it is driven by dimensions. A new wall thickness, hole pattern, board size or overall size is a quick revision, not a rebuild. HOW MY MODELS ARE BUILT, AND WHAT THAT MEANS FOR FILE FORMATS I build models parametrically on the OpenCascade CAD kernel, the same kind of solid-modeling engine that sits inside commercial CAD programs, and I render in Blender. The geometry is exact solid geometry, not a mesh. What this means for you: - You get clean STEP solids that import into any professional CAD system and can be edited there - I do not deliver native SolidWorks, Fusion 360, Inventor or Creo files with a feature tree. If your project strictly requires a native file with editable feature history, please tell me before we start, so nobody's time is wasted WHAT I DO NOT DO I would rather turn a job down than surprise a client halfway through, so here it is plainly: - I do not build or test physical prototypes. I deliver the files, and you, a print shop, a machine shop or a factory make the part - I am not a licensed or chartered engineer and I do not stamp drawings. For pressure vessels, structures, ladders, trailers and other regulated equipment I produce the model and the drawings. The code calculations and the approval must come from a qualified engineer - I do not run FEA, CFD or mold-flow simulation. I design to established design rules and state on the drawing what has and has not been analysed - I do not do architecture, BIM, interior rendering, PCB layout, or sculpted jewelry and character models - I work remotely only COMMON QUESTIONS Can you work from a sketch or a photo? Yes, as long as you can give me a few key measurements. I will ask for the ones I need. Can you modify my existing CAD? Yes. Send a STEP or IGES file and I can add or change features and issue new drawings. Will my manufacturer accept your files? STEP, DXF and PDF are the standard exchange formats. If your manufacturer has a drawing template or a standard they want followed, send it and I will work to it. Millimetres or inches? First-angle or third-angle? Whichever you need. Tell me at the start. How many revisions are included? We agree that per milestone in the quote. Small dimension changes are quick because the models are parametric. WORKING TOGETHER - Location and hours: Lagos, Nigeria (GMT+1). I usually reply within a few hours - Language: English - Confidentiality: I am happy to sign an NDA before you share details - Ownership: the design and all files are yours once the milestone is paid - Updates: a short written update with images at each milestone, so you always know where the project stands TO GET A FAST, ACCURATE QUOTE, SEND ME - What the part or product has to do, and roughly how big it is - How it will be made (3D printing, injection molding, CNC machining, sheet metal, welding, laser or router cutting) and in what material, if you know - Anything it must fit: circuit board outline, connectors, mating parts, standard components - What you need back: a 3D model only, or the model plus drawings, flat patterns and renders - Your deadline BEYOND CAD Through my studio, Colls Digital, I also build web apps and interactive 3D product viewers and edit product video. If you need the launch assets that go with your design, such as renders, an exploded-view animation or a 3D viewer for your website, the same person can deliver them. If your project is on the list above, message me with what you have. I will tell you plainly whether I can do it, how long it will take and what it will cost.
