Luxury Champagne Stopper 3D Design

We are developing an exclusive luxury champagne stopper / pouring attachment for high-end gastronomy and premium brands.

We are looking for a professional 3D product designer who can create:

1) A realistic industrial product design (luxury stopper)
2) 3D CAD model suitable for manufacturing (STEP / STL)
3) High-end photorealistic renders
4) A short product animation video with realistic fluid simulation

Product concept:

- Champagne bottle held horizontally in hand
- Special transparent luxury stopper attached to the bottle
- Champagne flows from inside the bottle, through the neck, through the stopper, and exits vertically from the top center into a champagne glass
- Inside the stopper: transparent liquid with floating gold flakes (snow globe effect)
- Very elegant, premium, minimalistic design (similar to Bang & Olufsen / high-end accessories)

Deliverables:

- 3D files (STEP + STL)
- Product design renders (4K)
- 5–8 seconds cinematic product video
- Technical dimensions suitable for injection molding (29mm bottle opening)
- editable CAD files, high quality renders, and optional short product animation.

Please show relevant product design / industrial design portfolio.
Please specify your experience with injection molded consumer products and provide examples of manufactured products.

This is a long-term project with follow-up phases possible.
