I will do 3d cad design, industrial design, 3d model for printing and injection mold


About this gig
FROM PRODUCT IDEA TO PROTOTYPE & MANUFACTURING!
Have a sketch, reference, or product idea but no clear path from concept to a workable product? Get your product design, industrial design, CAD design, 3D modeling and 3D rendering developed into a clear 3D product model you can review, prototype and take toward manufacturing.
WHAT I CAN DO
- Industrial & product design
- 3D CAD & mechanical modeling
- Concept development & refinement
- Prototype & manufacturing-focused CAD
- Product visualization & 3D rendering
- Design modifications & iterations
WHAT YOULL RECEIVE
- Detailed 3D CAD model
- STL, STEP, IGES/IGS & OBJ files
- Technical drawings where required
- Realistic 3D product renders
- Editable source CAD files where included
WHO I WORK WITH
- Inventors & startups
- Product brands & entrepreneurs
- Engineers & manufacturers
- Consumer, mechanical & home products
- Hardware, accessories & 3D-printing projects
From a rough sketch to a refined industrial product design, your model is developed around your dimensions, function and project requirementsnot a one-size-fits-all approach.
Have the idea but not the CAD? Send your sketch, dimensions or reference today and lets turn it into a product you can build.

FAQ
I only have a rough idea. Can you develop it into a product?
Yes. You don't need a finished CAD file or engineering drawing to start. A sketch, dimensions, reference images, existing product, or rough concept can be enough to begin the product design and CAD development. If key details are missing, they can be clarified before modeling starts.
Can the design be developed for both prototyping and manufacturing?
Yes. The CAD model can be developed with the intended prototype or manufacturing process in mind. Whether you're planning 3D printing, CNC machining, injection molding, or another process, share the intended method so the design can be developed accordingly.
What if my product has several components that need to fit together?
Multi-part products and assemblies can be developed as a complete 3D CAD assembly, rather than modeling each component in isolation. Dimensions, interfaces, mounting points, and component relationships can be considered so the complete product can be reviewed.
Can you improve an existing product instead of designing from scratch?
Yes. An existing CAD model, physical product, sketch, or reference can be used as the starting point. The design can be modified, refined, redesigned, or developed further while preserving the features that already work.
How do I know which package is right for my product?
Choose Basic for a straightforward single-part CAD model, Standard when you need detailed product CAD, technical drawings and renders, or Premium for more advanced product designs requiring assembly documentation and multiple photorealistic renders. For anything outside these scopes, message me firs
What happens if I need changes after seeing the first design?
Your package includes revisions so the design can be adjusted against your original requirements. To avoid unnecessary redesign, the key dimensions, references, functions, materials and intended use are reviewed before the CAD modeling begins.
