Lighting for Makerbot Replicator 5th Generation

*** Update 2017-01-07 ****
I added Light Rail, Side -2.0.stl
It seems the diffuser interferes with the ribbon cable at full extension so I modified the design to be more compact. The geometry is the same, but everything is pushed back about 1/2". The rails hang down a little lower, but it's still out of the way of any moving parts. It actually fits well in the under nitch, anyway.

I also hollowed out the rail so it saves on filament. Even though I used foam tape, it introduces a lot of acoustic vibration so I reduced contact surfaces. This reduces area for foam tape, which might still work, but I'm using hot glue for V2.0.

I also printed the new one in carbon fiber PLA for stiffness. The original light rail I printed started curling under thermal stress of the LED. We'll see how CF PLA fairs.

The front rail seems fine, but I'll be updating the design for filament-conservation as well as reducing contact surfaces to reduce vibration as well.

I'll also be modifying t
