Turn&lock Socket for Elements Lamp

This is a covered version of http://www.thingiverse.com/part:3404 with two parts : an outer bracket with hinges to fit with other Elements, and an inner part holding the lamp socket that locks into place.

This elaborates on http://www.thingiverse.com/thing:7836, making it easier to replace the light-bulb, and also fixing the dimensions so that the hook on the back of the socket is not obstructed.

It is designed to work with the decorative polyhedral Elements to build lamps for diffuse lighting http://www.thingiverse.com/thing:6281. The hook on the back of the lamp holder makes it easy to hang lamps flexibly around the room. I plan on attaching several truncated-icosahedral lamps to a chain which can be draped over other furniture. If all goes as planned, the plastic shell will also protect the light-bulbs, making it possible to leave these lamps on the floor with minimal risk. The goal is to design a diffuse light source that is both beautiful and resilient, so it can be moved
