Now, let's make this thing!
Step 1: Model the CCTV and centerpiece
The SketchUp file below has two mirrored versions of the CCTV in the same space. Rotate both together to get a new angle and hide one at a time for each image you need of it.
With the resulting images, flip one of the images so that they can be attached back to back.
As for the centerpiece, I recreated that in Illustrator.
