Parametric Product Design in Grasshopper

I’m developing a new product and need an expert who can translate my concept into a robust Rhino model driven entirely by Grasshopper. The goal is a fully parametric design: key dimensions must update cleanly, complex geometry should remain watertight, and the file structure has to stay organised for future edits.

You’ll start from my sketches and reference measurements, set up the complete Grasshopper definition, and deliver clean, layer-named Rhino geometry ready for downstream detailing or visualisation. Accuracy and clarity in the definition are critical—I should be able to adjust inputs and instantly see reliable results without manual fixes.

Deliverables
• Grasshopper file (.gh) with clearly labeled sliders and user-friendly inputs
• Rhino file (.3dm) reflecting the live parametric output
• One round of refinements after I review the first delivery

If you have a track record of product work in Rhino, understand best practices for parametric workflows, and are comfortable explaining your node logic, I’d love to collaborate.
