Not that this is all that complex and I've got most of it figured but there are some things I'm not sure about...
My kickstarter aluminum channel+diffuser arrived along with a small packet of parts. It appears there are two end caps that screw to the channel, and the diffuser slides in the top groves. There are two clips that I think are intended to clip the stick to something else, and a small acrylic rectangle with your logo screen printed on it.
Where does the logo rectangle go?
Does it matter which end the wires come out?
I assume you intend the USB cable to be permanently attached.
