Hardware nobody makes
Autopilot gears, hatch hinges, vent cowls, winch parts, instrument covers — recreated from a photo when the manufacturer stopped stocking them.
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.

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 reverse-engineer the geometry in FORMA, our parametric CAD engine, and print in the engineering material the job needs on a Prusa Core One L, sponsored by Prusa Research.

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, broken, or never made — we build it.
Mounts and brackets
Transducer mounts, antenna brackets, plotter housings, junction boxes curved to your mast section. Designed from your measurements, not a generic template.
Larger vessel work
Refit coordination, sourcing, fiberglass and structural work arranged through our partner network including High End Welding. You hand it over; we complete it.
Parts tested on Mr Jumpa
Every new fitting earns its place on our own 1977 Farr 38 before it is offered to your boat. Real offshore conditions, not a test bench.
The 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.

1977 Mr Jumpa — Farr 38, parts proven offshore
Fastnet 2025 — real offshore delivery
We sail the same water
Mr Jumpa competed in the Rolex Fastnet 2025. Parts we make for clients face the same conditions our own gear does. No parts are offered untested.
Built from a photo
No drawing, no CAD file, no problem. We rebuild discontinued and broken parts from a phone photo and a tape measure. Most quotes start with nothing more.
Steel when plastic won't do
High End Welding is our structural partner. When a fitting needs welded fabrication or steel, we bring in the right trade rather than forcing it through a printer.
Parametric CAD built here
FORMA is our own CAD engine. It generates manufacturable geometry from your exact dimensions — not a guessed mesh from a photograph alone.
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.
Straight answers
What kinds of boat repair do you handle?
Hardware and parts first: discontinued fittings recreated, broken plastic components replaced in stronger materials, mounts and housings custom-built. Beyond parts, we take on vessel projects as managed work: assessment, sourcing, coordination, and completion, including fiberglass and structural work arranged through our network.
My part is discontinued and nobody stocks it. Can you really make it?
That's our core business. Send a photo of the part or its remains with rough measurements; we reverse-engineer it and print it in a marine-grade material. Quote within 24 hours.
Do printed parts actually hold up on a boat?
Printed in the right material, yes: UV-stable ASA and PETG-CF are engineering plastics, not hobby filament. We sail offshore ourselves and test parts on our own 1977 Farr 38 before offering them.
Where are you, and do you travel?
New Brunswick, Canada, on the Saint John River. Parts ship across Canada. For the right job, the printer and the people come to the boat.
What does it cost?
Parts are quoted from open per-gram material pricing and usually land far below machine-shop or OEM replacement prices. Project work is scoped and priced before anything starts: no surprises.
What's broken on your boat?
Send a photo. We'll tell you what it takes to fix it, honestly, within 24 hours.
