Here's how to make your own...
You will then need to have access to a CNC router. I don't have one of my own, but use a local service, which also supplied the Gatorboard foam board which I've chosen to use for it's cost, relatively good durability and especially how light weight it is.
You will need six sections of half of the chandelier. All halves are identical. To make my chandeliers as large as possible, I was able to get two on a standard 48" x 96" sheet, so I required three sheets total to be cut.
In my builds, I've used 1/4" Gatorboard foam board, and the slots in the design are cut to accomodate that thickness. Each chandelier requires four slotted disks to hold each of the six sections into place. The slots are 1/2 the radius of the disk, with four matching slots on each chandelier section. Though I require only four of these disks per chandelier, I have plenty of spare room on my 4x8 sheet to cut extra, which is always a great idea to have spares!
Additionally, I have teardrop "crystals" cut and pre-drilled to be strung with loops of monofilament and hung from the two tiers of each chandelier section.
