Some quickies. As you probably know the top one is spring loaded and moves downward against spring force, then the notch aligns and when the spring is released, it notch engaged the k3's case.
The bottom is curved so you load the k3 an angle and then rotate up and to the left.
Their case is nice since it is all one piece with the light internal until pulled free. A light off the top center might be more even. I, at least, cannot read the letters on the graphite keyboard with the current light. It might be nice if it could illuminate the keyboard a bit better.
