metal flywheel 3d model

High-detail 3D model of a peripheral impeller wheel for a liquid pump. A flat, round metallic disk with a central stepped hub and straight radial blades on both sides. Key features to include: Outer diameter: about 126 mm. Blades: 32–36 narrow, straight, evenly spaced blades of uniform thickness. Blades start at about 1/6 of the diameter inward from the outer rim and extend to the outer perimeter. Symmetry: The entire impeller is fully symmetric about the mid-plane. Hub: Central cylindrical bore for a shaft, including two opposite flat key surfaces (double-flat shaft seat). Hub has accurately stepped concentric cylindrical sections (≈19–34 mm diameters). Front face: Two M6-type threaded holes, axial, placed symmetrically around the center on a circular pitch. Material appearance: Clean, machined metal with precise edges and smooth surfaces. Goal: A realistic, highly detailed, cleanly machined mechanical part.
