Ender 3 LED light bar

I know there are probably a million and one makes for an Ender 3 light source, but where's the fun in using someone else's design all the time? Plus I had a few white LEDs in my spares box and thought I'd give it a go.
The main design parameter was to keep it as simple as possible, hence the way it clips into the aluminium extrusion plus the simple 'clips' that keep the wire in place and away from the guide rollers (even though they had me wracking my brain for a couple of days to work out how to keep that simple too!).
