Foldable Compostable Cup Concept Design

I’m developing a plastic-free, single-use cup inspired by ideas like Unocup, but I want it made from molded pulp, foldable for easy storage, leak-proof once opened, and finished in a pleasant matte surface.

For this concept stage I need:
• two to three hand or digital sketches exploring different folding approaches that stay compact when collapsed yet assemble in a single intuitive motion,
• one clean 3D render of the concept we pick (SolidWorks, Fusion 360, Blender or any tool you’re comfortable with), and
• simple overall dimensions and basic specs so I can start initial talks with manufacturers later.

Manufacturing-ready CAD is not required right now; I’m after creativity, thoughtful geometry and clear communication of the folding mechanism. If you’re a newer industrial or product designer eager to add sustainable packaging work to your portfolio, this is a good fit. Please send any relevant samples of previous eco-friendly or paperboard/pulp designs with your bid.

The schedule is tight—about a week from kickoff—so clear progress updates are appreciated.
