Two-Stage Helical Gear with Metallic Insert

A highly precise, engineering-grade 3D CAD model render of the plastic compound helical gear seen in image_0.png, designed for direct use in a CAD software environment for 3D printing. The model features the specific opaque white engineering plastic material, with its characteristic surface texture and minor wear marks as in image_0.png. The gear must strictly adhere to the following dimensions: ​Overall Structure: A concentric, two-stage helical gear. ​Center Bore: A through-hole with a diameter of 6.07mm, including the specific dull metallic insert seen in the top bore in image_0.png. ​Large Gear (Bottom): Outer Diameter (OD) of 26.50mm, 48 teeth, with a width/thickness of 5.05mm. ​Small Gear (Top): Outer Diameter (OD) of 17.40mm, 31 teeth, with a teeth section height of 11.00mm. The helical teeth on both sections must have the correct and matching helix angle, oriented as shown in image_0.png, and be modeled with an accurate involute profile. The render is presented in an elevated three-quarter view on a neutral, technical grey studio background, with measurement lines and numerical callouts (Ø26.50mm, Ø17.40mm, 5.05mm, 11.00mm) clearly labeled, similar to a professional technical drawing or datasheet. The focus is sharp on the gear's geometry, material, and dimensions. The lighting is even and highlights the gear details."
