I will provide mechanical design, dfm engineering and functional product prototype
John Berry
About this gig
Need mechanical design that works and can be manufactured without costly surprises? Get a clear path from your idea to a part you can test and produce.
Many buyers lose weeks to slow replies, designs that fail at production, or files a manufacturer cannot read.
Rework and vague drawings raise your costs.
Every design is checked for function, fit, and manufacturability before it reaches you, so your next step is simple.
WHAT YOU GET
- DFM engineering review that cuts production cost and avoids tooling or machining rework
- Technical drawing sets with dimensions and tolerances your manufacturer can read without questions
- 3D CAD models ready for printing, machining, or molding
- A functional product prototype to test fit, movement, and usability before you invest in volume
- Simpler assemblies with fewer parts and easier production
- Material advice matched to your budget and quantity
HOW IT WORKS
- Send your project details, sketches, and requirements
- Get fast, responsive communication throughout
- Receive on-time delivery, then review and request revisions
Message me before ordering so we can confirm your scope, requirements, and the best package for your project.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

I specialize in 3D CAD design, product development, and 3D modeling using SolidWorks and Fusion 360. I create detailed product models, mechanical components, functional parts, and technical designs based on sketches, reference images, and project specifications. Whether you need product concept development, 3D modeling, CAD modifications, or manufacturing-ready designs, I focus on accuracy, practical solutions, and clear communication to meet your project requirements.

FAQ
What do I need to start a mechanical design project?
A sketch, reference photo, or written description is enough. If you have dimensions, materials, or a target budget, share them. The more detail you provide, the fewer revisions you will need.
Can you design a part that is easy to manufacture?
Yes. Each design is checked for manufacturability before delivery, so you avoid features that raise cost or cause production problems.
What is a DFM review and why do I need one?
It checks your design for features that are hard or expensive to produce. Catching them early saves you from tooling changes, machining rework, and delays.
Will my technical drawings be usable by a manufacturer?
That is the goal. Drawings include dimensions and tolerances so your manufacturer can quote and produce without back-and-forth questions.
Can you help with a functional product prototype?
Yes. You get a design built to be tested for fit, movement, and usability before you commit to larger production.
What file formats will I receive?
Common formats for 3D models and drawings. Tell me the format you need before ordering so we can confirm it.
Can you work from my existing design or idea?
Yes. I can improve an existing design or build a new one from your concept. Message me first so we can confirm what is needed.
How many revisions are included?
Revisions depend on the package you choose. Changes within the agreed scope are covered. Larger scope changes can be handled through a custom offer.
How long will my project take?
Delivery time depends on complexity and the package. Message me with your project details and I will confirm a realistic timeline before you order.
Do I need to message you before ordering?
It is recommended. A quick message helps confirm your scope, requirements, and the best package, so the order starts smoothly.
