LightBottlev2

An other solution for the light bottle challenge. Work In progress. This is different from the other one (http://grabcad.com/library/lightbulb--7) in that, that it needs silicone insulation, but it lights under the line of the roof. The system is easy to assembe, needs no tools (except for the two m4 screws) and any part can be replaced easy, tool-free. The solar panel, and the bottle can be placed anywhere. v1.1: cables are now inside the tube. (thanks to Martin Spencer-Ford ) v1.2:Redesigned battery, and solar panel holder, for lesser material consumption. Minor changes on the bulb, for the same reason. Redesigned led holding case, for better light distribution.
