A set of LEDs 2 red 2 yellow are set into some the gribblies in the neck, used to help add some detail and distract the eye from seeing that it is a PVC threaded joint. They pulse at different rates to simulate different 'plasma' power conduits working under different loads. Also seen here is a length of electroluminescent wire wrapped into the PVC threads, it is movie era/ Next Generation but we took liberty here since out of all the other colors it looked best under both dark and normal room light levels.J-57 Techmages Sci-Fi Models TOS Star Trek Completed Space Station neck joint
Also seen is a close look at the Lower [Cargo] Shuttle Bays
There are 4 lower cargo shuttle bays; the K-7 seen in the Original Star Trek Series had a single darkened bay/opening at its bottom stub.
Word has it that the original model had a inscription that said, "Welcome to the K-7 Space Station, Now Go Away"
Here we have several different bays each is marked for a different function and each has its own a funny saying;
"Welcome to Jefferies Station
Now Go Home
Customs Inspection Area"
"Hard Hat Area
"If you can read this you have been fatally irradiated
The customs bay has a long shuttlecraft with several black view ports (a passenger shuttle).
The maintenance bay has some smaller 'half' back shuttles; one is mounted on a piece of thick plastic fiber optic, so it appears to be flying out of the bay
Other bays have various shuttles sitting about on their pads. Every bay has 4 pads, with some of the pads printed up to appear to have oil/fluid stains.
Note the Theme music plays out a speaker set on the motor (it will be encased in some foam to reduce motor noise), the bridge and navigation FX play out a speaker housed in the station's main saucer section.
