About this gig
Is your plastic product ready for injection molding?
I design and optimize plastic parts, enclosures, and product components for injection molding with practical DFM principles to help you avoid common manufacturing problems before tooling begins.
I can work from your existing CAD, sketch, dimensions, or product concept and develop a manufacturing-focused solution with attention to:
- Wall thickness
- Draft angles
- Ribs & bosses
- Snap-fits & assembly features
- Undercuts & parting considerations
- Tolerances and fit
- Injection-molding manufacturability
Gig offers:
- DFM Analysis
- Injection Molding Ready CAD
- 3D CAD design
- Plastic Enclosure Design
- Product Redesign
- Technical Manufacturing Drawings
- Prototype to Production
- Additional Plastic Part
- Assembly Design
- Material Selection
- Extra Revision
You can receive production-ready STEP, STL, SolidWorks/Fusion 360 CAD, and technical drawings depending on your package.
Ideal for startups, product developers, engineers, inventors, and manufacturers.
Have an existing plastic part that needs optimization? Send it over and Ill review the scope before you order.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

FAQ
What do you need to start the project?
Please send your sketches, dimensions, existing CAD files, reference images, or product requirements. The more information you provide, the more accurately I can develop the design
Can you design a plastic product from a sketch or idea?
Yes. I can develop your concept into a functional 3D CAD design suitable for injection molding
Can you optimize my existing CAD for injection molding?
Yes. I can review and modify your existing model for DFM, including wall thickness, draft angles, ribs, bosses, snap-fits, and manufacturability
Do you design plastic enclosures for electronics?
Yes. I can design housings and enclosures with features such as PCB mounts, screw bosses, snap-fits, covers, openings, and assembly interfaces
Do you provide DFM analysis?
Yes. I can identify common injection-molding issues and recommend practical design improvements before tooling or manufacturing.
Can you work with SolidWorks or Fusion 360?
Yes. I can work with SolidWorks, Fusion 360, and common CAD formats such as STEP, IGES, STL, and other compatible files
Will the final design be ready for manufacturing?
The design will be developed with injection-molding manufacturability in mind. Final tooling and production requirements should still be confirmed with your manufacturer
Can you design multiple plastic parts that assemble together?
Yes. I can design multiple components and consider their fit, interfaces, clearances, and assembly requirements
Can you sign an NDA for my product?
Yes. You can provide your NDA before sharing confidential project information, and we can keep all project communication and files within Fiverr
