Wavetray

One wave function, defined parametrically in Rhino Grasshopper, produces the tray's grip, rim and stacking at once, without a single detail drawn on its own. It's CNC-milled in coordination with the workshop, with tool radius and clamping carried as constraints straight in the parametric model; a model is only worth something once it knows those manufacturing limits, and that's exactly where it got awkward.

The same curve takes on a different job on the wall: what forms the grip on the tray holds the cups there. That's what led to a web configurator, letting people generate their own variants.
