First ever attempt at working with fibre optics. I watched a few YT videos to see how other modellers achieved this and I thought I would try it myself. There was one particular video that was really helpful.
I pre-drilled 0.5mm holes in the cockpit panels while I waited for the 0.5mm filament to arrive from China. I ordered a couple of metres of it and I only just came away with enough. The average length of each filament was about 10cms. I wanted to give myself enough leeway for trimming and mistakes. After threading them through the holes, I flared the ends with a tea light candle then I divided the filaments roughly in two and passed each branch through some 5mm heat shrink tubing. I then used some Elmer's Glue to fix the heat shrink tubing in place. I then lined the underside of the nose with aluminium foil (bearing in mind I primed it as well with black) then I passed both branches into a final single piece of heat shrink tubing and fixed the LED to the other end, ensuring that there was no light bleed from the tube. Once it was all glued in place, I tested it and was surprised at just how successful it came out! Sandwiching the underside of the cockpit proved to be a bit of a challenge but I got there in the end and with a bit of putty and some touching up, I think it will look good. I'll also touch some transparent colours to some of the lights in the cockpit to give a little variation. You can see the 6 plug expansion board there which I've been using with a USB portable charger to test everything. Later on, all the lights will be plugged into a pair of 12 plug expansion boards which I'll mount inside the main hull.
Now, the reason I cut the cockpit door out of the back panel is answered here. I placed a red LED on the ceiling of the collar that connects the cockpit to the main hull. I'm hoping, when lit it will cast an appropriately ominous "Sith-like" glow on Darth Vader and you'll be able to see it when you peek through there.
