Grasshopper Parametric Product Model

I have a finished product design in a Rhino 3DM file and now want the same geometry rebuilt exclusively through Grasshopper. The shape is straightforward, so the focus is on setting up a clean, well-named definition that recreates every part of the model with native Grasshopper components—no baked geometry, no external scripts.

You will receive the 3DM reference, and I will check the result by toggling parameters and comparing it side-by-side in Rhino. Accuracy to the original form, tidy organisation of the node network, and clear grouping/annotations are all important.

Deliverable
• One .gh file that reproduces the supplied product design completely parametrically

If you have solid experience crafting Grasshopper definitions for product models, this should be a concise job.
