Job Description
3D CAD Designer Needed for Consumer Personal Care Product — Manufacturing-Ready STEP Files
ABOUT THE PROJECT
We're a US-based startup developing a small consumer personal care product. We have a complete written specification, hand sketches, and engineering input from prospective overseas manufacturers. We need a 3D CAD designer to translate this into clean, manufacturing-ready STEP files we can hand off to factories for tooling and sample production.
The product is patent-pending. Full design details will be shared under NDA after engagement begins.
WHAT WE NEED
1. 3D model of a small molded silicone component (STEP / .STP format) — primary deliverable
2. 3D model of a soft foam outer shell with matching internal cavity (STEP / .STP)
3. 2D technical drawings with full dimensions and tolerances (PDF) for both components
4. Native source files (SolidWorks, Fusion 360, Rhino, etc.) for future revisions
KEY REQUIREMENTS
- Files must be manufacturing-ready — appropriate for silicone injection molding and foam molding
- Tolerances, draft angles, and wall thicknesses appropriate to the manufacturing methods
- Design must consider a bonded interface between the foam and silicone components
- Files must open cleanly in standard CAD software for factory review
EXPERIENCE WE'RE LOOKING FOR
- Strong portfolio of consumer product CAD work
- Solid understanding of injection molding, especially silicone
- Familiarity with foam molding is a plus
- Beauty / cosmetic / personal care product experience is a plus
- Clear English communication (files will be reviewed by overseas factories)
WHAT YOU'LL RECEIVE FROM US (under NDA)
- Detailed written product specification
- Reference figures showing the product from multiple angles
- Engineering input we've already gathered from prospective factories
- Direct access for questions throughout the project
TIMELINE
2-4 weeks from project start to final files.
CONFIDENTIALITY
This is a patent-pending product with active factory outreach. Sensitive design details and specifications will be shared only after engagement begins, under a written NDA.
WHAT TO INCLUDE IN YOUR PROPOSAL
1. Portfolio examples of similar consumer product CAD work, especially involving silicone or molded components
2. Your proposed software / approach (1-2 paragraphs)
3. Estimated timeline
4. Any clarifying questions you have
Looking forward to your proposals.
