🎯 Turning Your Product Ideas Into Production-Ready Designs I'm a manufacturing engineer who bridges the gap between design and production. With 3+ years of hands-on experience in CNC machine shops, I know what it takes to transform concepts into manufacturable products that actually work on the factory floor. I specialize in creating precise engineering drawings, robust CAD models, and detailed manufacturing procedures that save you time, reduce errors, and keep production running smoothly. Whether you're launching a new product or optimizing an existing manufacturing process, I deliver engineering solutions that make your job easier. ✨ What I Bring to Your Project My unique background combines design expertise with real-world manufacturing knowledge. I've been on the shop floor, managed engineering projects, and worked directly with customers, so I understand both the technical requirements and the business side of getting products made. My core services include: • 2D Engineering Drawings (production-ready prints with GD&T) • Solid CAD Modeling and Assembly Design • Engineering Documentation and SOP Creation • Manufacturing Process Optimization • 3D Printing Solutions and Prototyping • Machine Maintenance Planning and Documentation 🛠️ Technical Expertise Engineering & Design: CAD Design | Mechanical Engineering | 2D Engineering Prints | 3D Modeling | Assembly Design | GD&T Manufacturing: CNC Machining Knowledge | Manufacturing Engineering | Process Documentation | Quality Control | 3D Printing Project Management: Engineering Project Coordination | Customer Service | Technical Communication | Procedure Development 🏆 My Approach to Success I believe great engineering isn't just about technical accuracy—it's about clear communication and practical solutions. Every drawing I create is designed to be easily understood by machinists and manufacturers. Every procedure I write eliminates confusion and prevents costly mistakes. I work best with manufacturers and product designers who value precision, clear documentation, and efficient processes. My goal is to become a reliable extension of your engineering team, delivering quality work that meets deadlines and exceeds expectations. 🌟 Ideal For • Small to large-scale manufacturers needing engineering support • Product designers requiring production-ready CAD models • Companies developing manufacturing documentation and SOPs • Businesses seeking mechanical and manufacturing design expertise 📍 Work Preferences I'm based in the United States and primarily work with US clients, though I'm open to international projects where clear communication is assured. I focus on projects valued at $250+ where I can deliver meaningful impact and build lasting professional relationships. 🚀 Let's Build Something Great Ready to move your project forward with precision engineering and clear documentation?

I run Hattendorf Design & Solutions, a small manufacturing-focused design consultancy specializing in CAD, tooling, and design-for-manufacture. My work sits at the intersection of engineering design and the shop floor—helping clients turn concepts, legacy parts, or problem designs into manufacturable, production-ready solutions. I don’t just model parts to look good on screen. I design them to survive machining, molding, casting, inspection, and assembly. What I Do Best ✔ Production-Ready CAD & Drawings Parametric CAD models and clear manufacturing drawings built for real-world tolerances and processes. (SolidWorks, AutoCAD, Creo) ✔ Tooling & Mold Design Design support for: Casting tooling and patterns Injection and permanent molds Fixtures and manufacturing aids ✔ DFM & Manufacturability Reviews Identify tolerance risks, draft issues, parting problems, and cost drivers before they hit the shop. ✔ Reverse Engineering & Reconstruction Turn scans, physical parts, or incomplete data into clean, editable CAD ready for production and inspection. ✔ Prototyping Support 3D printing and validation workflows to de-risk designs prior to tooling or release. Recent Project Experience Designed tooling and molds for aluminum and polymer components, reducing lead times and rework ✔Reconstructed legacy parts and tooling into modern parametric CAD for repeatable production Supported machine shops and foundries with designs meeting strict tolerance, inspection, and DFM requirements ✔Delivered drawings and models that integrate smoothly into CNC, QC, and inspection workflows My Background I’m a Design Engineer with 3+ years of hands-on experience supporting casting, molding, and machining environments. I’m completing my degree in Mechatronics Engineering, with emphasis on mechanical design, manufacturing processes, and quality systems. This combination lets me bridge the gap between: Engineering intent Manufacturing reality Cost, lead time, and quality constraints How I Work Clear scope and deliverables Practical, production-aware design decisions Clean files, revision control, and documentation Responsive communication and realistic timelines If you need manufacturable designs, tooling support, or a technical partner who understands how parts actually get made, I’d be glad to help.

Hi, my name is Zack and I’m a mechanical engineer. I have approximately 5 years of work experience involving work with CAD design, 3D printing, design for manufacturing, and project management. I have used Freeform, Solidworks, Inventor and Fusion 360 design software. I primarily use Autodesk Inventor and Fusion 360 today. I graduated from Northern Arizona University in Fall 2020 Cum Laude with a degree in mechanical engineering. I’m currently working as a senior manufacturing engineer/project manager where I take customer requirements, convert them into 3D models for approval and take them through the manufacturing processes. I am responsible for all projects through each step of our processes in a sheet metal environment so I am familiar with laser cutting, CNC machining, bending, welding, assembly, and powder coating. I also tutored mathematics in college where I learned crucial problem solving skills.

I am a 30 year old Mechanical Engineer who has worked in the consumer products field as an Engineer, in education as a high school Engineering teacher, and a freelance product designer and writer. I am well versed in all fields involving technology, and continuously research my crafts to stay competitive. I am organized, detail oriented, and communicate well.
