I will create 3d cad product design for injection molding, dfm and manufacturing


About this gig
Welcome to my Gig!
I don't just turn sketches into 3D models; I design parts with manufacturing in mind from the start. Whether you have a rough concept, existing CAD, or a product that needs refinement, I'll develop the geometry around injection molding, fit, assembly, and practical DFM requirements so you can move confidently toward prototyping and production.
What I can help you with:
- Injection molding-ready 3D CAD product des-ign
- Plastic product development from sketches, images, or concepts
- Existing CAD modification and redesign
- Design for Manufacturing (DFM) analysis
- Wall thickness optimization
- Draft angle and fillet optimization
- Ribs, bosses, snaps & mounting features
- Snap-fit and press-fit components
- Parting-line and moldability considerations
- Undercut and ejection feasibility checks
- Assembly and component fit optimization
- Multi-part plastic product des-ign
- Prototype-ready designs for 3D printing
- CNC and manufacturing-ready CAD
- Reverse engineering from measurements or reference parts
Process:
- Send requirements
- Review & planning
- 3D CAD modeling
- DFM optimization
- Design review
- Final manufacturing files

FAQ
What do you need to start?
A sketch, dimensions, reference images, existing CAD, or any available product information.
Can you design my part specifically for injection molding?
Yes. I can optimize wall thickness, draft, ribs, bosses, fillets, undercuts, and other key DFM details.
Can you work with an existing CAD model?
Yes. I can modify, repair, redesign, or optimize your existing model for manufacturing
What file formats will I receive?
Depending on your requirements, I can provide STEP, STL, IGES, DWG, PDF drawings, and native CAD files.
Can you design the injection mold too?
Yes, mold-related work can be handled as a separate custom project after the product design and requirements are reviewed
