I will develop 3d cad models with dfm, technical drawings and realistic renders
Jonas R
About this gig
A product should do more than look good in 3D. It should fit together, communicate clearly to suppliers, and account for how it will be made.
I create 3D CAD models with design for manufacturing (DFM), technical drawings, and realistic product rendering for mechanical parts, enclosures, and consumer products. Whether you have a sketch, reference image, or existing CAD file, I develop your design around its dimensions, function, material, and intended manufacturing process.
Depending on your agreed scope, you can receive:
- Detailed 3D CAD models of parts and assemblies
- DFM review with practical design adjustments
- Technical drawings with dimensions and agreed tolerances
- STEP and STL files for supplier review or prototyping
- Realistic renders to visualize your product
The DFM review considers features such as wall thickness, clearances, assembly fit, and process limitations. Design decisions are aligned with your requirements and any manufacturer feedback you provide.
Please message me before ordering with your references, dimensions, material, and manufacturing method so we can confirm the scope and deliverables.
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.

Hi, I’m Jonas Robert, a CAD designer specializing in 3D CAD design, design for manufacturing (DFM), product rendering, and 2D technical mechanical drawings. I help inventors, brands, and startups develop detailed parts, assemblies, and product visuals for prototyping, manufacturing reviews, and presentations. My focus is accurate dimensions, practical design, clear communication, and attention to detail. Let’s develop your product ideas with precise CAD models, clear drawings, and realistic renders.

FAQ
Can you improve an existing CAD model for manufacturing?
Yes. I can review your model for issues such as wall thickness, clearances, assembly fit, and difficult-to-produce features. Please send the file and intended manufacturing method so I can assess the changes needed.
What if I have not chosen a material or manufacturing method?
Share your product’s purpose, expected quantity, and functional requirements. We can discuss suitable design directions, then confirm the material and process before completing process-specific DFM work.
Can you design an enclosure around my electronic components?
Yes. Please provide component dimensions or CAD files, mounting points, connector locations, and access requirements. These details help me plan the enclosure fit, openings, and assembly.
Can you create CAD models from sketches or reference images?
Yes, provided we have enough dimensions and functional details. Images help establish the shape, but critical measurements are needed to define an accurate model.
Does a DFM review guarantee that my manufacturer will accept the design?
A DFM review helps identify manufacturing concerns for the agreed process. Your manufacturer should confirm the final design against their tooling, equipment, materials, and production requirements.
Will my technical drawings include manufacturing tolerances?
Drawings can include agreed tolerances for critical dimensions and mating features. Please identify fit requirements and share any supplier standards before work begins.
Will I receive an editable CAD file?
STEP files support CAD exchange, while STL files contain mesh geometry. If you need a native CAD file with an editable feature history, please confirm the software and file format.
What happens if my manufacturer requests changes?
Send their marked-up drawings or written feedback. Changes within the original scope can be handled through the included revisions; a new manufacturing process or major redesign may require additional work.
Can you check whether moving or mating parts fit together?
I can review modeled clearances, alignment, and assembly interference within the agreed scope. Physical testing, load calculations, and engineering simulation should be discussed separately if required.
Can I request only CAD design, drawings, or rendering?
Yes. You can request a specific deliverable or a combined service. Send your references and requirements so I can quote the scope you actually need.
