A detailed 180 mm Francis turbine engineering model for 3D printing.

This model is ideal for hydropower enthusiasts, students, classroom demonstrations, and mechanical-model collectors. The turbine uses real bearings so the runner can rotate smoothly after assembly.

Required hardware:
• 2 × 6000 bearings (10 × 26 × 8 mm)
• 4 × M3 × 8 mm DIN 912 screws

Test-fit the bearings and assemble the runner for a functional mechanical display.

A great STEM project for learning about Francis turbines, hydropower, and rotating machinery.
