Trailed Seed Drill Air Seeder STL 3D Print Model

The Trailed Seed Drill is a highly detailed 3D model of a large-capacity trailed pneumatic air seeder with an extended folding boom frame, multiple seed distribution hoses, and a central hopper unit mounted on a wheeled chassis with a drawbar hitch. The model captures intricate mechanical components including disc coulters, press wheels, hose routing trees, marker arms with end discs, and the full seed metering assembly visible from all angles. Ideal for agricultural dioramas, scale modeling, and display purposes, this model is supplied as a ready-to-print STL file. All eight orthographic and perspective views are included to guide assembly and painting of the printed parts.

Print settings

FDM printing is recommended for larger structural parts such as the hopper, frame, and boom arms; resin (MSLA/DLP) is strongly advised for the fine seed hoses, disc coulters, and press wheel details. Print the boom sections flat on the bed with tree-style supports for the hose bundles; the central hopper unit prints best upright. Use 0.1–0.15 mm layer height for detail parts and 15–20% infill with PLA or PETG for structural components. Supports are required for overhanging hose runs and marker arm brackets.
