Every boat older than about fifteen years has at least one: the part the manufacturer stopped making. Autopilot gears, hatch hinges, instrument covers, winch components, vent cowls. The boat is fine; one ounce of discontinued plastic is holding it hostage.
Rebuilding starts with what you have: the broken part, or a photo and measurements of where it used to live. We model it, correct the weakness that killed the original (they almost always break the same place), pick a material rated for where it lives, and print it.
The result is usually stronger than the original and costs a fraction of a machine-shop one-off. Send a photo of yours through the quote page and we'll tell you within 24 hours whether it's printable.
