I designed a modular set of components to make navigationlights for my sailing yacht:
Additional components are leds and a CC/CV converter for electronics and a borosilicate tube for glass.
All other components are professionally 3d printed in PA12, polished, painted and hydrodipped for carbon look:
For mounting the lights on different positions I had stainless steel parts water-cut, designed with shaper:
In total I produced 10 navigation lights.
