1.Multi-Function Tool kit: The purpose of these designed tools is to have optimized tools that will cover different tasks during our stay.

1.1. The hammer tool and also a multi-screwdriver. We wanted to incorporate several tools at once to have the availability to create one piece using less material, the hammering can be utilized not only for the regular tasks we daily have but also helping to accomplish any other task, like making a hole, or digging. Dimensions: 287mm length hammer, 38mm length screwdriver tools.

1.2. The 1.5 OZ multi-purpose tool spoon, fork, knife, can and bottle opener (see Figure X.) is made of plastic for astronauts can eat and cook. Also, astronauts can use it for their daily science works. It is portable and simplifies astronauts' lives in the Martian environment. Its dimensions are ‎18 x 3.6 cm

2.Folding Furniture: Bed-wardrobe and desk:

Space optimization is key on base camps, this is why we are proposing a Murphy Bed with a study desk to have a wardrobe that includes a bed and a desk at the same time, making it very useful to keep clothing and any other personal items handy every day, Its dimensions are 2x 1.4 meters.

Steel for mechanical parts and PETG for the desk and other pieces were selected while choosing this design.

3.Mars Base Camp:

This camp is divided into four equal parts each part has a diameter 1.99 meters and 1.98 meters of altitude. Taking of printing constraints possibilities. The base is made out of regolith, the lower dome is made out of concrete, the dome structural superior base is made of steel 3D printed pipes (which have a multi-purpose functionality) and a PETG red superior cape covers the roof.

It also has integrated concrete tunnels that can be used to connect with more base camps for other needs.

Dimension: 3.98 m diameter (when 4 parts are joined together)

4.Replacement rover wheel: 

The replacement rover wheel allows the rover to explore, swerve and curve in the martian fields. The rim is made of martian aluminum for support, with hexagonal holes cleats for traction. The tire is made out of rubber and the triangles that cover the rim are PETG red. Its size is 39.5 centimeters, and one complete turn of the wheel drives the rover 1.63 meters.

To give ourselves an idea of ​​the contest, its objective, the additional considerations, and the consultation materials we have at our disposal, thanks to the collaboration of the NASA SPACE APP CHALLENGE TEAM, we reviewed the “Outfitting a Mars Habitat: A 3D Print Challenge” profile.

As we searched through the resources provided, we started with brainstorming finding out that astronauts on Mars need four main core things: multi-functional tools, modular furniture, a critical surface infrastructure foundation, and a replacement rover wheel.

The first consulted database was the ARC 3D Models Database. We were inspired to create our replacement wheel by M2020_WHEEL_DESKTOP_MODEL-5inch, Curiosity 'Scarecrow' Test Rover, Curiosity Rover, Perseverance, Multi-Purpose Precision Maintenance Tool, Wrench, and Hammer models.

Other significant sources of inspiration for creating 3D tools, furniture, and infrastructure were Project Olympus: Off-World Additive Construction for Lunar Surface Infrastructure paper which helped us to build an additive critical infrastructure, and NIST Additive Manufacturing papers, and other extra materials that we found on the internet. 

Initially there were only two members on the team, however we incorporated 2 more, and at the end only 3 worked on it. Even though not everyone was into this challenge at the beginning since we thought we did not have enough experience on this field, we were able to complete it.

We can say that at the end every single person was able to provide great and efficient ideas, help modelling and coming on different areas to finalize the project.

At the beginning we had some specific ideas that changed during the Journey, due to timing and feedback received from the mentors, as well based on the mission purposed that we wanted to be accomplished at the end.

2 out of the 3 members did not have experience in hackathons as it was the 1st doing it and we are incredible thankful for the opportunity which certainly opened our minds way more to understand that there are resources available on where we can continue working and doing research going forward (Open Code), besides getting closer to the Space Industry which is one of our main passions.

The experience has been quite challenging, we wanted to make sure we provided specific, valuable and efficient tools, and even though time was a bomb we truly enjoyed it, there were times where we felt a lot of pressure but at the same time, we felt happy with the results.

A key point on this challenge was to work very close, constant communications and live calls to make sure we were going the right direction and that everyone was in sync with the ideas and proposals shared, everyone had the opportunity to provide all type of ideas making it a flexible and nice working group even though some of us did not know each other before.

We would like to thank the Main Costa Rica Leads for the constant support to us and a special thank you the Mentor who worked with us providing feedback, they are:
