gyroid lattice sculpture 3d model

continuous tapering Archimedean helical ribbon to create a natural chimney effect for passive airflow, built-in Laplace pressure gradients for rapid inward and downward droplet transport, and a high-surface-area gyroid lattice for superior droplet nucleation. Total height: 200 mm Helical ribbon: continuous Archimedean spiral with 7 full turns Base diameter: 220 mm tapering linearly to 80 mm at the top Ribbon dimensions: 38 mm radial width, 6 mm base thickness Inward bevel: Slight 12° taper on the inner ribbon face to drive droplets toward the center TPMS Gyroid Lattice: Schoen gyroid triply periodic minimal surface integrated throughout the ribbon volume Cell size: 8 mm Strut thickness: 1.2 mm Porosity: 70-80% max surface Ribbon & spirals and lattice Connected to Central Drainage System with an 8 mm diameter central hollow axis. Subtle helical micro-grooves (1.5 mm deep) acting as an Archimedean screw for transport to the base while connecting all the parts into a single object
