Emily the Engineer is no stranger to 3D printing unusual items, but her latest creation just might be the craziest yet. It could be the world’s largest 3D Benchy, which refers to a small, boat-shaped model that is typically used to test and benchmark 3D printers.
Emily first started by printing smaller 3D Benchy models for troubleshooting purposes, before eventually scaling up to the life-sized version consisting of smaller sections that had to be glued and melted together with a soldering iron. A small electric motor was added, enabling it to be taken to the open water after a few additional flotation devices were installed.

There’s a bunch of small boat-builders that use bed sheets, diluted epoxy and coats of exterior house paint instead of fiberglass. It’s very cheap and sometimes works better than fiberglass, depending on what you’re sealing. When the boat is already largely waterproof, it’s a decent option for smoothing the hull and adding just a bit of extra assurance it won’t leak,” said one commenter.
