Hello @jsgrobsun and welcome to the forum!
Can you explain us a little more about what are we seeing here on the picture? 
We are setting up a model to hold cameras to be aimed at a subject placed in the centre. connections and hardware to be held in the bottom, except for the cameras to be placed around the sphere. sphere is 30 inches in diameter and we are using miniature cameras
Have you already choose which cameras are you going to use?
