Overhead Camera Mount Rig with Dual Ball Head Super Clamp (Tilehurst RG30)

I am looking for a desktop overhead camera mount rig suitable for top-down filming and photography. Ideally, something similar to the NEEWER NK003 model (But open to options).

To be able to create overhead videos and project demonstrations, so I need a solid rig that can hold a DSLR camera securely above my workspace.
