Well, it's just about complete. Textures have been adjusted, markings added, as well as lights. Here are some views:
As you can see from the markings, I have tried to distinguish it from K-7, which is a civilian station. We never saw what kind of markings a Starfleet facility would carry, so I've used my imagination. The "WP" stands for "Warehouse Pod."
How big is it? Jefferies specifies 1800 feet from top to bottom on his sketch. Here are some scale comparison views next to the Enterprise and DSS K-7:
This has been a really fun project. For years I have wanted to bring Matt Jefferies' more ambitious, original concept for K-7 to life. I think it makes a fine Starbase in its own right.
