Stefan worked with us on a design with many manufacturing and compliance requirements, where mistakes would be very costly, and showed us how the designed parts would meet those requirements with simulations.

About this gig
"I help founders, startups and small businesses turn physical product ideas, references or early requirements into professional 3D CAD concepts for prototyping and further development."
This gig combines product design and mechanical engineering thinking. Depending on the project, I can support product shape, outer shell, ergonomics, internal layout, component packaging, basic mechanical structure, assembly logic and prototype-oriented CAD development.
I can work outside-in, starting from the product form and user experience, or inside-out, starting from components, space requirements and technical constraints.
All packages include 3D CAD work, review visuals and standard export files such as STEP and/or STL.
The packages are reference points only. Since every physical product is different, I usually review your brief, references, dimensions and expected deliverables first, then create a custom offer with clear scope and milestones.
Please contact me before placing an order so we can define the right scope for your project.

FAQ
What do you need to start the project?
Helpful inputs are sketches, reference images, dimensions, existing components, product goals, use case, materials, and any technical requirements. If you do not have everything prepared yet, we can start with a concept/CAD direction phase.
Should I place an order directly?
Please contact me before placing an order. Every physical product is different, so I usually review the scope first and create a custom offer based on the complexity, timeline and required deliverables.
Are the packages fixed scopes?
The packages are reference points. Larger or more complex product development projects are usually split into clear custom phases or separate orders.
Which file formats do you provide?
Standard deliverables usually include STEP and/or STL files, plus review images or previews. Other export formats can be discussed before the order.
Are native editable CAD source files included?
Native CAD source files are not included by default. They can only be provided if agreed before the order and may require an additional fee.
Does this include technical drawings?
Basic technical drawings may be included in the Premium package depending on the scope. Full manufacturing drawing packages are usually quoted separately.
Can you create a physical prototype?
Yes, physical prototyping, 3D printing, assembly and basic testing can be offered separately after the CAD phase, depending on the product, materials and required components.
Is the design manufacturing-ready?
I can create prototype-oriented and manufacturing-conscious CAD with practical design decisions. Final mass-production approval, certified engineering validation, tooling design or full DFM documentation must be agreed separately.

Another phase with a quality delivery. The subassemblies of the master object all appear very ideal, along with the snap-together technology that Stefan developed.
