mechanical gear model 3d

Create a 3D printable mechanical model. 1. Place 6 vertical cylinders in a row on a vertical support rail. 2. Each cylinder is 50 cm tall and contains a piston that can slide up and down. 3. On top of each piston, attach a buoy. The buoy is larger in diameter than the cylinder. 4. Each piston and buoy is clearly connected — the buoy must push the piston vertically. 5. Add a continuous chain that runs behind the cylinders. 6. The chain wraps around two large vertical sprocket wheels (50 cm diameter). 7. Place a third vertical sprocket wheel in the middle of the chain path. 8. This third sprocket has a hollow axle for routing air tubes. 9. Show air tubes connected to each cylinder but passing through the third wheel’s axle. 10. The assembly is immersed in water (water level shown). 11. Include all movable parts as separate pieces for 3D printing. 12. Show correct mechanical relations: chain around wheels, pistons inside cylinders, buoys connected to pistons, air tubes routed without tangling.
