This is an underground Martian base composed of six main parts: four sections that make up the habitable areas, a central circular part where a parabolic mirror is placed to reflect sunlight into the base, and a transparent dome that protects the base from asteroids.
Inside each section, there are two floors where the colonist inhabitants live their lives among hydroponic crops, scientific experiments, and moments of relaxation in common areas. Meanwhile, on the surface, rovers and excavators extract a precious multicolored, filament-like substance from the rocks, which powers the entire Martian base.

The colonists have only recently arrived, so the furnishings are still quite basic, but soon files will be sent from Earth to create new structures to add to their base.
If you'd like to stay updated on the stories of this base and its inhabitants—and if you also need the files to upgrade your own Martian base—you'll find future updates here.

Features:
This diorama includes some moving parts: the excavator has a movable shovel. The elevators are designed to rotate, creating the effect of ascending and descending between floors. A light is placed on the garage entrance. More features will be added.

Printing Tips:
I’ve included a file for the “transparent” dome. However, be aware that even when printed in PETG, it turns out quite opaque and requires supports. So if you have one, consider using a 24.5 cm transparent bowl (or something of similar size) to achieve a better visual effect.
The floors of the base will not be transparent either: it's better to use the floor files as templates to cut out transparent plastic sheets. You may want to glue some parts for a stable display of your base.
