The LED lamp uses the same basic geometry ashttps://pinshape.com/items/428... but with the twisted slats flipped to form a symmetrical pattern. That description gives info about how I developed the geometry for all these designs. This lamp is the same size as smaller one mentioned above, but becuase it has an additional set of slats it required 15 3/4 hours to print using a layer heigth of 0.200 mm and a print speed of 100 mm/sec. FOr this print I used transparent yellow filament which doesn't photograph well, but most any transparent or solid light colored filament will work OK.

This lamp accommodates either a battery operated or wall powered "puck" LED light. This blog page has links for all the wall powered parts needed and shows to hot hook everything up: http://birkbinnard.com/blog/wall-powered-led-lights/. For battery powered puck lights just go to any large home improvement store or simply Google "LED puck light".
