Innovative Dual-Chamber Cap Design

I have developed an early concept for a dual-chamber flavour-release cap aimed at the food-and-beverage sector, and I’m ready to turn it into a working mechanical assembly. The goal is a moderately detailed internal mechanism that clearly shows how each chamber moves, seals, and locks, while remaining practical to manufacture.

You’ll be modelling in SolidWorks or Fusion 360—whichever you know best—so the files stay fully parametric for future tweaks. Once the CAD is complete, I need the design prepared for plastic 3D printing, along with guidance on the most suitable printing process (SLA, SLS, FDM, etc.) and any quick-fit components such as O-rings or snap features that improve sealing.

Deliverables
• Fully editable CAD assembly and drawings
• STL files optimised for printing
• A brief build guide outlining print orientation, supports, and post-processing steps
• Recommendations for at least one iterative prototype cycle

The schedule is roughly four to eight weeks, and I’m flexible on milestone structure. Please include a portfolio link that highlights previous prototype-ready mechanisms or closure systems so I can see how you’ve solved similar challenges. I look forward to collaborating and bringing this cap to life.
