Build montage showing a fiberglass sailboat being built. In this episode all the fiberglass is completed. Some 3D printed parts are used in the completion of the hull. They are available on Thingiverse: https://www.thingiverse.com/thing:467...

I use inexpensive polyester resin for this project.
I am sure there are better ways to do this...
This seems like a decent tutorial:    • Fiberglassing Tutorial with Greg Hahn...
