Generic Spider Gear Casing Differential Housing CAD Model 3D print model

This is a 3D CAD model of a generic spider gear casing, commonly used in automotive differential systems to house the bevel or planetary gears (also known as spider gears). The design represents a simplified but realistic geometry suitable for educational purposes, mechanical assemblies, or FEA/CFD simulations.

The model is built in CATIA and includes features such as gear pockets, mounting surfaces, and structural contours typical of a differential gear housing. It is provided in multiple formats for maximum compatibility.

Features:

• Generic differential spider gear casing geometry
• Designed in CATIA with clean and structured features
• Ideal for transmission system layout and assembly studies
• Suitable for FEA structural simulation or topology optimization
• Compatible with most CAD platforms via STEP and IGES

Applications:

• Automotive drivetrain simulations
• Transmission system design
• Mechanical engineering education
• FEA stress or vibration testing
• CAD libraries for assemblies or part replacements

File formats:

• CATIA .CATPart
• STEP (.stp)
• IGES (.igs)
• STL (optional for meshing or visualization)
