How to make a vertical laptop stand from laser-cut acrylic

When my wife is working from home, she likes to sit at a proper desk with a monitor, keyboard, and mouse instead of hunching over her laptop. To make it easy, I set up an "umbilical cord" of power, USB, and display connection to plug in and off she goes. To free up room on her desk she lays her 13" Macbook Air on the floor which is always kind of awkward. To resolve this, I thought a space-saving vertical laptop stand could help, much like one of these made by Twelve South or Rain Design.

But it's no fun to buy one; let's design and build one from scratch out of laser-cut acrylic!
