Hello all!
This is my Modular Mars Base design. This base is highly customizable in terms of the positions of the modules as well as what goes in them. Due to the dangerous atmosphere and climate of the red and barren planet, it would be best to live in an enclosed area, where traveling outside is minimal. This is why each module can be connected with one another. These modules are also elevated off the ground. The reason for this is due to the dust storms that occur on Mars that usually lasts for weeks. It would be disastrous if the bases were to be completely enveloped and buried in dust.
Some other reasons for the design of the Modular Mars base:

1. Dome-shaped roofs
   The dome shaped roof provides the structure with more stability in high winds when compared to flat geometrical shapes. The dome structures also distribute the stress evenly, which provides greater strength and resistance to the high velocity winds of Mars.

2. Dome-shaped solar panels
   The outermost layer of the dome would be comprised of solar panels. The round shape allows a higher efficiency when collecting energy than the conventional flat solar panels as domes have a greater surface area. Another perk of these solar panels would be their resistance to high winds. As they attached directly to the roofs, they would not experience turbulent winds that could rip them off.

3. Hydraulically elevated modules
   The elevated modules would help prevent the base from inevitably being buried by the sandstorms of Mars. The multiple legs of the elevated modules also allow for any necessary relocation of the base if the area becomes too dangerous live in. The ski-like shape of the legs also allows for the stability of the module.

4. Customizable arrangements
   Due to the elevated platforms, the modules can be moved to any arrangement based on the needs of the inhabitants.

5. Connected modules
   Due to the dangerous conditions of Mars' atmosphere, leaving the base often would be dangerous. To prevent this, the modules are able to be connected which provide a safe passage to and from each module. A majority of the modules have at least 4 exits, which may be open or closed to another module. More and more of these modules can be added to create a larger base once the population of the civilization increases.

6. Garage modules
   These relatively large modules allow for the storage of supplies. Not only are they storage units, they can also hold vehicles for the exploration of the newly colonized planet.

7. Modules
   Since the arrangement of the base is customizable, the modules itself should be customizable too. Each module can be made into whatever one pleases. Some ideas for the interior of the modules may include: a recreational center, living quarters, a cafeteria, a greenhouse, research lab/center, energy and oxygen supply, communications center, and many more.

*In some of the pictures, there are extruded cuts in the "doorways". These cuts are for the connection between the different modules and the connectors once 3D-printed. Yes, this means the 3D printed version can be customizable. (Connectors & Exits - Male, Everything else - Female)

Thank you for reading!

I began with drawing drafts on Solidworks and eventually came up with the current design while adding several fixes and tweaks here and there. This design was mostly inspired by the Halley VI research stations, which are based in the Antarctic region.

You can either download each part separately and print them to put together, or you can download the assembly files for a finished base.

To assemble, the connections of the "Connector" or "Exit" must be put into the available slots of the modules.
