I will do 3d cad design and mechanical product design for manufacturing and cnc
Robert S
About this gig
Great mechanical products begin with CAD that gets the details right. Accurate dimensions, functional geometry, proper fit, and well-structured files can make the difference between a concept that stays on screen and one that moves successfully into prototyping or production.
I provide 3D CAD modeling and mechanical design for product concepts, mechanical parts, enclosures, components, and assemblies. Projects can be developed from sketches, dimensions, reference images, existing drawings, or CAD files.
SERVICES INCLUDE:
- 3D CAD modeling and mechanical design
- Mechanical parts and assemblies
- Product and component modeling
- CAD models for 3D printing and prototyping
- CNC and manufacturing-focused models
- 2D technical and engineering drawings
- STEP/STP, STL, and editable source files
- Existing CAD modifications and design improvements
Each project is developed around its intended application, dimensions, and provided specifications, with attention to accuracy, clean geometry, and organized deliverables.
Please message me before ordering to discuss the project scope and requirements.

Hi, I’m Robert Schultz from Berlin, Germany, a product designer with a background in Product Design from Hochschule Wismar. I help startups, inventors, brands, and jewelry businesses turn ideas into professional design assets ready for presentation, prototyping, manufacturing, or production. My services include patent drawings, product design, 3D CAD modeling, product rendering, and jewelry CAD design. Send me your idea, sketch, or reference, and let’s turn it into a finished design.
FAQ
What information do you need to start my CAD project?
Please provide available sketches, dimensions, reference images, drawings, existing CAD files, and the intended use of the model. The more accurate the information, the better I can define the project scope.
Can you create a 3D CAD model from a sketch or reference image?
Yes. I can develop CAD models from clear sketches, drawings, reference images, or dimensioned concepts. Complex projects may require additional measurements or details before work begins.
Can you design mechanical parts and assemblies?
Yes. I can work on individual mechanical components as well as multi-part assemblies. Please send the project details first so I can evaluate the complexity and recommend the appropriate package.
Which CAD file formats can you deliver?
Depending on the project, files can include STEP/STP, STL, and editable source files. Let me know which format your manufacturer, engineer, or 3D printing service requires.
Can the CAD model be used for 3D printing?
Yes, models can be prepared with 3D printing in mind. Please tell me the intended printing process, dimensions, and any specific requirements before the design begins.
Do you provide technical or engineering drawings?
Yes. Dimensioned 2D technical drawings can be included when required. Please confirm the drawing requirements before ordering because the scope varies between projects.
Can you modify an existing CAD model or mechanical design?
Yes. I can update dimensions, geometry, features, or other design details in existing CAD files when the supplied file format allows the required modifications.
Can you prepare designs for CNC or manufacturing?
CAD models can be developed around the intended manufacturing process and provided specifications. Please share the material, process, tolerances, and manufacturer requirements when available.
