Parametric Rings
Each ring in this collection is driven by its own parametric algorithm — its design DNA — so every dimension is generated rather than modeled by hand.
The critical advantage: resizing changes only the inner diameter. Wall thickness, surface geometry and proportions remain precise across all 22 sizes, from 14 mm to 22.6 mm.
Designs are optimized for printing with a variety of methods: FDM, Resin, SLS or my personal favorite for this case — wax printing + metal casting.

Drag the sliders to explore the ring's parametric design space in real time.
Parametric design enables precision at scale — the algorithm regenerates every size without distorting the design.
-
Parametric system
Each design is a standalone Grasshopper definition that generates the complete ring — profile, surface geometry and sizing — from a set of input parameters.
-
Size without distortion
Generates a full range of 22 sizes, from 14 mm to 22.6 mm, while holding wall thickness and critical features constant.
-
Design for casting
Optimized for on-demand wax printing via Shapeways, then cast into metals — including silver and gold-plated brass.
