Jet Ski Steering Nozzle
Reverse engineered from a cracked original
INTERACTIVE
Spin the actual part
The real geometry, both ends of the job: the exact model that was printed in PA12-CF10, and the raw 3D scan of the cracked original it was rebuilt from. Drag to rotate.
LOADING 3D…The steering nozzle — the component that directs a jet ski's thrust to steer it — had cracked and was no longer usable. The part is no longer produced: the only replacements left are complete used assemblies on the secondhand market, starting around $2,000. So instead I reverse engineered it: the original was 3D scanned and rebuilt as a clean, parametric CAD model.
The replacement was printed in PA12-CF10, a carbon-fiber-reinforced nylon chosen for its stiffness, strength, and durability in a wet, high-vibration environment. It has more than proven itself since: the nozzle has shrugged off real abuse and kept the ski running strong through many hours out on the lake.
HOW IT WENT
- 01
Scan
Captured the failed part's exact geometry
- 02
Reverse-engineer
Rebuilt it as clean, parametric CAD
- 03
Print
Printed a functional replacement in PA12-CF10
