Stand for Lenovo Yoga Tab 3

A stand for the 8" Yoga Tab 3 in portrait orientation.

I love this versatile tab for several reasons, including its built in kickstand for viewing in landscape orientation. But I surf sites mostly in portrait and I needed a way for it to be supported.

There are two files with one being tilted further back than the other. I prefer the more upright one but of course more tilt would be safe if it gets a little knock.
