DoubleTwistLamp1

This lamp is designed for an LED "puck" light. Battery operated lights are about $4 each; simply do a web search for "puck light". This blog page tells where you can get wall powered lights that work very well: http://birkbinnard.com/blog/wall-powered-led-lights/.

This print took 21 hours 2 minutes at a print speed of 100 mm.sec and layer height of 0.400 mm. It uses the same basic design as https://pinshape.com/items/379... so it may be that you have to use the Slic3r slicer to slice it. For details why this is the case see that page or, for more information, this one: http://birkbinnard.com/blog/do-the-twist/.
