This large lamp is based on a super ellipse shape that has equal length and width. A super ellipse is formed by a version of the equation for an ellipse that is modified to give it squarish corners. The top view photo shows what this shape looks like. This lamp is designed to hold any one of several LED lights called "puck" lights. You can get these powered by either batteries of wall power. This blog page has links for wall powered lights that work well: http://birkbinnard.com/blog/wall-powered-led-lights/. For many more options just Google "led puck lights."

Due to it's large size and the requirement for the printer to make many small moves it took nearly 50 hours to complete this print. It printed at 90 mm/sec and a layer height of 0.200 mm.
