<p>I don't know if this helps, but I was once told to use "Up or Right" as a mount/orientation guide for anything without polarity. </p>
<p>So, in the case of the resistors, pick a side and aim it Up or Right, then your project will be both consistent, and visually pleasing. I'm my case, I usually use the tolerance band for this orientation. The result is resistors with the "code" side always facing the same directions.</p>
<p>In the case of the Drone Lab, this also happened to work perfectly for the 10 switches as well, using the little stamped graphic on the side of them as the "Up or Right" indicator.
