I found it on eBay, sellers name is archmedianet. It's 3D printed and there are others available for various tablets. My tablet is a Samsung galaxy tab 4, the sunshade originally comes with a second piece (adapter) to fit the standards OEM device holder. As you can see, I have modified my RC with a center mount and a square jellyfish tablet holder. I asked the seller if I could purchase the sunshade only as I did not need the adapter, he agreed and I got it for a lesser price. I had to use a Dremel tool to widen the opening a few millimeters to fit my tablet holder.
