Summary

I thought this concept might make a good LED table lamp so it has an open bottom to accomodate an LED light. The top "surface" is a saddle-like shape defined by a 3D Loft surface used as a trimmer for the cylinders. Here's a 51 sec. video that shows the shape pretty well: https://www.youtube.com/watch?v=6WwBwQudrcE. The print completed in a little less than 16 1/2 hours using a print speed of 70 mm/sec and a layer height of 0.200 mm.

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."
