Construct the central vertical axis using a robust hardwood dowel and a set of nylon bearings to allow for smooth 360-degree rotation. This pillar serves as the sun-like anchor for the remaining planetary seed tiers.

Fabricate three concentric rings of varying diameters from laminated plywood strips, ensuring each is lightweight yet durable. Each ring functions as an individual tray for different seed types, mimicking the orbits of planets around the central stem.

Incorporate delicate brass support struts to connect the rings to the central axis, angled slightly to provide stability against gusting winds. Use marine-grade finish to protect the mechanical junctions from moisture exposure.

Install a weather-resistant copper finial at the pinnacle of the structure to act as a rain guard for the central bearing assembly. This decorative topper ties the celestial aesthetic together while keeping the internal gears functional and dry.
