Sailing Marks for Training
thingiverse
To go along with the handy little vessels I created (http://www.thingiverse.com/make:128233), I designed these distinctive signs. Affix a tiny magnet to the bottom and they will stick securely to most chalkboards, making it possible to chart courses, outline rules and conduct tactics training. I have access to only one single extrusion printer, so I was forced to number them with a marker by hand. I'm uncertain what would be required for dual extrusion printing, but it's extremely appealing to envision these prints completed using dual technology.
