Custom Parts
If it existed once, I make it again.
Broken fitting, discontinued handle, obsolete hardware, or a part that never existed. Send a photo, sketch, broken original, or measurements.
How It Works
Photo. Model. Print. Fit.
Send what you have
A photo, sketch, broken part, measurements, CAD file, or clear description is enough to start.
I design it
The part is modeled for the vessel, the load, and the environment before it gets printed.
It gets delivered
The part is printed, checked, shipped, or installed directly when I am deployed on site.
Materials
The material matches the job.
ASA
Deck hardware, cockpit parts, exterior fittings, and UV-exposed surfaces.
PETG-CF
Chemical-resistant parts, engine-room fittings, and structural interior use.
PA-CF
High-load, high-vibration, high-temperature parts where failure matters.
Polycarbonate
Impact-resistant guards, covers, housings, and protective parts.

Example
The Cherbourg machine shop had not started.
Osprey's mainsail track gate fell overboard in Cherbourg. The local machine shop quoted over $800 and a multi-week wait. The Core One L printed the replacement in 8 hours.
Testimonials
The result matters.
“If I had a 3D printer, you'd take a nap and wake up to the part done.”
“We were delighted and relieved to have you aboard Ken. Your extensive knowledge of the vessel was essential to getting us to Fastnet, and I know all of the others felt the same way as I about your invaluable assistance. Fair winds my friend.”
