How It Works
Marine Solutions, Designed by Makers Who Know the Sea
MarineLab3D connects boat owners who need a part with designers who know how to make it. Every file is reviewed before publishing, most designs are parametric — you set the dimensions, we generate the file — and everything is delivered as a digital download you can print at home or through a print service.
For Boat Owners
Step 1 — Find the part
Browse by category — plumbing & pumps, deck & rigging, anchoring, electrical, galley, interior and more — or start with the For Free collection. Each product page shows the article code (Art. ML3D_xxxx), the recommended materials and print settings, the file formats included and a 3D preview you can rotate.
Step 2 — Set your dimensions
On designs marked Customizable, click Customize dimensions: choose hose diameters, thread sizes, lengths, number of hooks or holes, even a custom name to emboss. The 3D preview updates live, so you see exactly what you will print before you buy.
Step 3 — Download & print
After checkout your STL is generated to your dimensions and the download link arrives by email (it also stays available in your client area). Print it on your own machine following the settings on the product page — see the Materials Guide — or, if you don't have a printer, request an instant quote from your download page: the model is sent pre-loaded to our partner Craftcloud, which compares print services worldwide and ships the finished part to you. The Where to Print page also helps you find a local print shop.
Step 4 — Fit it
Every design is made for real installation on real boats, with wall thicknesses and clearances chosen for FDM printing in PETG, ASA or nylon. Check the fit, pressure-test plumbing parts before use, and leave a review from your client area — it helps the next boat owner choose.
