Structure Sensor for 12.9-inch iPad Pro Accessory Bundle

What is this?

The necessary cable and connector to use my Structure Sensor with a 12.9" iPad.

Why did I buy it?

I wanted to still be able to use my Structure Sensor and unfortunately couldn't until I bought this insanely priced upgrade kit ($70!).

It comes with a cable that is slightly longer than the one I had an a professionally 3D printed mount to stick to my iPad. I think I could have printed out my own if they made the file available, but they don't. I really feel like Structure screwed me here.
