I did up a stand for the JBL slot and ring radiators. I would like to cast these in clear acrylic, but will settle with ABS 3-D printing for now.
This is very marketable and the JBL flat metal stands cost $100/pr. If I can do them in acrylic and get half that, I could sell a ton on the bay. They would even sell in black ABS for the right price.
My original I made out of wood and use in my home theater.
