I started with a very small model using a scale of 1 mm = 4 amos. At this scale the entire model is about the size of a business card and stands 1" high, just the right size to fit in your pocket.

Aside from the eight or so chambers that I squeezed in, you can also see the curtain of the Antechamber, the two ramps leading up the outside of the Heichal Building, and the little doorways in the chambers of the Women's Courtyard.
The photos show a model I printed on my Lulzbot Mini 3D printer using yellow HIPS plastic. I plan to work on a larger scale model with even more details.
There is also a handy floor plan to point out what goes where:
