Ignis Fatuus

As I was in need of some amount of little colorful lights, I decided to make something to light one color cycling LED diode with two AG13 battery. And results are here:

• Virvatuluke.stl - Very first project and was surprisingly ready to use right after printing. Just cut diode's shorter leg 5 millimeters more shorter and insert it shorter leg toward to center. Then bend that shorter leg down and insert batteries - negative side toward to bended leg. And that's it.

• Virvatuluke 2.stl - As with first design is unconfortable to switch LED off, second one was born with little "switch". Unfortunately, when printed with PLA, it is quite fragile. ABS is recommended for this design. This version is also 2 millimeters lower than it's predecessor.

• Virvatuluke 3.stl - Expansion of second design to use 3 battery cells. Alas it is not good idea to use it, as 4.5 volts is little bit too much for LED to handle and shortens it's lifetime by price of brightnes.
