UPDATE 6/20/12: Added Netfabb'ed versions.
This is a press-fit lamp shade for inexpensive 12V 9-LED T10 automotive lamps. I believe these are sometimes called "wedge lights," and are used as turn signals or interior lights. (I got mine on ebay for $1.50 for two, shipping included.)
They're made for 12V DC operation, which is convenient for reprappers, and they don't really need to be fastened to the frame if you're using solid core wire.
These things are quite bright, and the shade does a great job of keeping the light in one place and not in your eyes. They require about 225mm of 3mm filament each (about a nickel).
v1.0 - The original prints shade down, with no built-in support structure
v1.1 - Prints base down with extra support on the shade-to-base transition. (On left in photo printed in white.)
v1.2 - Prints shade down with simple built-in support structure. (On right in photo printed in white.)
