Laptop Stand V2.0

My Dell XPS13 finally gave up the ghost, and my new Dell XPS15 was too large for the old [laptop stand](https://www.thingiverse.com/thing:2035696), so I extended the old design out to the volume limits of my Ultimaker 2+. I also made the pieces a little bit thinner so that it didn't take up as much space in my bag when disassembled for traveling.
