UPDATED: Thanks to commenter @SupahMinah_226750 who asked where the staircase file was - I had uploaded the wrong model! I've uploaded the correct staircase, which wraps around the heptagonal building.
Super fast print jail / hab model with optional spiraling staircase.
Print the habs quickly, top down, using vase-mode / spiralise outer contour mode.
A quick drybrush with a metallic paint will have them on your tabletop in no time.
The staircase stacks / clicks together to fit round the habs, but can stand alone or be used with other scenery.

The author marked this model as their own original creation.
