Hi, I'm Justin Johnson, but you can call me J.J. I help inventors, startups, and businesses turn product ideas into practical, production-focused designs. From consumer product development and injection-molded plastic parts to functional enclosures, 3D assemblies, and technical drawings, I focus on creating clear, well-structured CAD solutions that consider real-world functionality and manufacturing needs. My goal is to understand your requirements, solve design challenges, and help move your project forward with confidence. Let's build something that works.

FAQ
Do I need to provide existing CAD files?
Existing CAD components are preferred. Sketches, photographs and reference drawings can be reviewed, but reconstructing missing geometry may require a custom order.
How many components can you assemble?
Each package has a defined component limit: 3, 8 or 15 component instances. Larger assemblies require a custom quotation.
Can you create an exploded view of my product?
Yes, an exploded view can visually separate the supplied components while maintaining their assembly relationships.
Do you provide technical engineering drawings?
Technical drawing sheets can be included according to your package. Required dimensions and specifications must be supplied or agreed upon.
What file formats can I receive?
Available formats will depend on the agreed deliverables. PDF, STEP, DXF and native FreeCAD files can be offered once their export and delivery have been verified.
Will I receive editable CAD files?
Editable native project files can be included when agreed upon before ordering.
Can you work with complex mechanical assemblies?
Yes, provided the project is within the confirmed scope of the service. Please send your files first for a complexity assessment.
How many revisions are included?
Revisions depend on your selected package. They cover reasonable changes within the original project scope.
Are manufacturing-ready drawings included?
Standard technical drawing sheets are not automatically equivalent to fully validated manufacturing documentation. GD&T, tolerance analysis, certification and other advanced requirements must be discussed separately.
Can I request a custom assembly project?
Absolutely. Send your component files, assembly requirements and drawing specifications for a custom quotation.
