Cymatics photography stand

The holes in the top of the shelf are for 5mm Led lights and the cavity is for the wires to set below the shelf. The poles make the height of the camera adjustable as to how close or far away it is and the speaker cavity is for a 4in sub woofer 3 1/8 inches from top left hole to top right hole center and 4 ½ inches to hole center diagonally. Diameter of hole 3 5/8 and plenty of depth. I use Dayton audio 4 in woofer for mine with a light wight plastic bowl painted matte black. The holes are all M3 screws and feel free to play with it. I added the side platforms and light holes in the second version which I will upload asap
