Plantronics / Poly PLT 5200 Office holder / bracket for Ergotron Notebook Tray

I am a big "clean desk" fan and have thus moved my headset and wireless phone charger to another level - just below my notebook.
The notebook resides on an Ergotron notebook tray. The adapter for the Plantronics Voyager 5200 office base is clamped onto the notebook tray. The clamp is thin enough to have the notebook trays "fingers" still maintain the notebook (also bigger ones than the depicted Air) in place.
The cables may be hidden underneath the notebook and can be routed invisibly through the Ergotron arm.

There is also a clamp for a belkin dual wireless phone charger: https://www.thingiverse.com/thing:6119560

For ease of print I printed this in black PLA+.
