Work in progress: I will also be creating templates for the layer that will connect the light fixture to the cardboard cylinder. More pictures and assembly tips to come.

Description of files:
23 arcs - This file contains 23 arcs whose inner and outer edges each have a different radius. As such, they can't be laid out very efficiently, so the laser will take about twice as long to cut these, but they are a little more visually appealing. I'll be using these to form the bottom two layers since that is the only layer where the cardboard thickness is visible.

30 nested arcs: This file uses a 17" diameter circle for the outer arc, and the same for the inner, so it doesn't have uniform thickness, but allows the arcs to be laid out very efficiently for the laser to cut. Since the outside edge of one arc is the inside edge of the next, the laser does almost half the cutting.

fixture: The fixture layer is designed to have the same 17" diameter outside circle, but has connections leading to a smaller circle designed to fit an Ikea Hemma light fixture which can be had for $3.99 (http://www.ikea.com/us/en/catalog/products/10175810/)

1. Cut the cardboard: ensure that corrugation of cardboard is aligned such that light can flow through the corrugation perpendicular to the long side.

2. Assemble rings: five arcs make up each layer of this lamp. I found it easiest to form the first two layers simultaneously: Set two adjacent strips on the lame layer next to each-other and glue a third strip on top of them so that it is covering up the inside half of each of the two strips on the base layer. Continue going around the circle in this fashion.

3. Stack as many layers as you want for the desired height, which will also depend on the thickness of cardboard used.
