I've been working on this on and off for the past few weeks. It's a composite of the original K-7 model (Datin) and the one shown on DS-9 (Jein). The main reason for this is I prefer (most of) the shapes of the original but the availability of DS9 model references is the most abundant.
The "saucers" are made to open and I'll be designing some sort of modular storage system to go in them.
Primary Module diameters (min/max) are 799.916'/824.686'. There are two numbers because of the overlapping hull structure (which is what allows it to open).
First some orthographics...
Now with the test lighting...
