Boat repair · Marine repair
Boat repair starts with the part nobody sells.
Discontinued hardware recreated, custom fittings built to your boat, and vessel projects managed start to finish. From people who sail offshore.
Most boat repair stalls on one missing piece: the fitting the manufacturer stopped making, the bracket that never existed, the plastic housing that fails every second season. We fix the part problem first — from a phone photo and a measurement, in a marine-grade material that outlasts the original — and we take on the bigger project when you want it off your plate entirely. Parts arrive by mail; when the job needs someone on deck instead, we travel to the boat. Browse the parts catalog for fittings in stock.
From a phone photo to a part on your boat.
- 01
Send a photo and a measurement
A phone photo of the broken or missing fitting and a rough measurement. If the part is gone entirely, describe where it belongs on the boat. That is enough to start.
- 02
Quote in 24 hours
A person who prints every day replies with a fixed price, the material chosen for the environment, and a ship date. The quote explains the material choice in plain language.
- 03
We rebuild it in marine-grade material
We rebuild the geometry in FORMA, our parametric CAD engine, and print in the engineering material the job needs.
- 04
Shipped from New Brunswick
Printed in New Brunswick and shipped across Canada within days of approval. For the right project, the printer and the people come to the boat.
Discontinued hardware
The part nobody makes anymore.
Autopilot gears, hatch hinges, vent cowls, winch parts, instrument covers — recreated from a photo when the manufacturer stopped stocking them, in a material that outlasts the original.

Custom fittings
Mounts and brackets, built to your boat.
Transducer mounts, antenna brackets, plotter housings, junction boxes curved to your mast section — designed from your measurements, not a generic template.

Proven offshore
Tested on our own boat first.
Every new fitting earns its place on Mr Jumpa — our 1977 Farr 38 that ran the 2025 Fastnet — before it's offered to your boat. Real offshore conditions, not a test bench.
Read the storiesThe right plastic for salt, sun, and load.
Material is chosen for the environment the part lives in and explained in every quote. We do not default to the cheapest option.
| Material | Best for |
|---|---|
| ASA | UV and salt exposure — outdoor hardware, deck fittings, anything in the sun |
| PETG-CF | Stiffness and load — brackets, mounts, and structural fittings that cannot flex |
| TPU | Seals, gaskets, flexible covers, cushioned mounts |
All materials are priced per gram and listed in every quote.
A shop that has been to sea.
Boat repair is one of the things 3D3D does — alongside software, web design, private AI, and field services. The same offshore experience and FDM capability runs across all of them.
