3D CAD Designer Needed for Consumer Product — Manufacturing-Ready STEP Files

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.
