Short bottom tablet stand

Remixed from [MKingery](https://www.thingiverse.com/MKingery)'s [Delta Stand v2](https://www.thingiverse.com/thing:4946573). I wanted something that took up less space it so I could place my iPad directly below my monitor and use the space in front of it.

The images show the 70° stand frame. This worked best for my viewing angle. Both of the others are still quite stable. The 100mm spacer is just about perfect with my 11" iPad Air.
