Last year, I have a solo exhibition of 3D print art in China. See https://www.shapeways.com/forum/index.php?t=msg&th=37819 This is one of the lamps.
Model is half of the ball, because the complete ball could not put the light inside, if print only half of the ball, can be placed on the mirror, lamp inside, It looks like a ball effect. If print two hemispheres, that get them together, one-time LED lights inside, can use transparent line hanging, like stars floating in the sky, very beautiful. Is this show, in my solo art exhibition. Such as photo show.
