In the early stage, I was just playing with the structure of standard. The base I made was a circle by connecting with 6 little PVC pieces. Each piece has degree. Therefore, it will become into a circle shape. Except those little PVC part,  I also have a long one which is around 35 inches. This is what I used for the main standard. On the one side of this part is the light bulb, and another side is the circle base.
