Miniature LED track lighting

With my partner, I'm building a tiny museum called [The Mμseum][museum]. We wanted to have a track lighting system similar to what one would find in a full-size museum. This lets the curator light pieces individually to help set off works in different ways. Each spot light is posable and has a can to create a crisp light cone.

This is a miniature track lighting system using standard through-hole 6mm LEDs as the light sources. The tracks themselves are simply stiff wires that run in parallel along the ceiling, holding the lights in place with magnets. This is designed to have 5V 1A rails and can support up to 25 LED spot lights.

**Note**: the notch to mark the polarity shown in the photos is inverted from the files here. After creating the photographed ones, I realized that it'd make more sense to publish with the notches matching that of LEDs (marking the negative/cathode instead of the anode).

The source files of the openSCAD files are in the [The Mµseum git repository][mu
