High-Level Project Summary
We generated CAD designs shown in stl format of a variety of tools, furniture and other elements that will be produced by 3D printers with materials such as Martian regolith, metal and plastic, these will help and facilitate the survival of the astronaut on the red planet. We managed to solve the problem thanks to the fact that these designs are made based on an exhaustive maximization of resources and conversion of tools into multipurpose, this taking into account the essential needs of the astronaut and the lack of objects in the original context.

Detailed Project Description
The project consists of a variety of CAD designs shown in stl format that will be produced by 3D printers that will allow the astronaut to survive optimally and manage to work in his 1 year mission despite the scarcity of materials and adverse conditions he faces.
We use three different materials to print the different designs, among them we have Martian regolith, plastic and metal, the latter is the product of melting the regolith and process it chemically, it should be noted that we propose that in the habitat there is already a machine that is responsible for this work, on the other hand, the plastic is the result of the chemical process through which the CO2 from the Martian atmosphere passes.
Some of the benefits that this project offers is the great maximization of resources that we have in everything produced and how efficient it is for the astronaut's mission.
We have 4 different types of metal screwdrivers that are assembled to a single handle made of plastic by a magnet. This is achieved by an artificially processed metal to become a magnet.
The mini drill motor also works with a magnet assembly system to a single plastic handle and 5 different metal parts for various uses.
The crowbar is one of the most multipurpose tools we designed, by assembling the sturdy handle with different metal accessories mechanically we get a saw, axe, hammer, weight for exercise, golf club for the astronaut to distract himself and a broom for habitat cleaning.
To finish with the part of the tools we have two tweezers that are also assemblable with 4 different tweezers each handle for both precision and more common uses.
On the other hand we have a gym area in which the astronaut will engage in physical exercise to maintain their physical and mental health. We designed a treadmill among the machines in this area that is mechanical.
The furniture also has a variety of functionalities apart from the conventional one, such as a table that contains a puzzle in its body to distract the astronaut and make him have fun.
Addressing the problem of the rover's damaged wheel we managed to design one that having the ideal weight, size, shape and mechanism manages to meet the necessary requirements to make the rover work again, among the characteristics of the wheel we have that it left a recognizable pattern in the sand so that we know where the rover passed, it has a closed outer face so that stones and dirt do not enter and we also have a thick tread.
We also have different furniture that facilitate the survival of the astronaut in his habitat as tables, bed, chairs, etc..
We hope that our designs will be efficient, useful and will make the astronaut finish his mission successfully.
We use Solidworks and shapr3d for this work.
Standards:
Standard for screwdrivers: ISO 6789-1:2017
Standard for hammers: DIN 1041
Finally we managed to make a website that encompasses one of the objectives that we consider very important because it touches on the theme of Space Apps, breaking the boundaries between people and space. With our website we managed to get closer to more people who want to learn more about our project and the challenges of this competition.
Space Agency Data
We use many resources provided by the NASA website, specifically from the following links:
https://nasa3d.arc.nasa.gov/models
https://www.nasa.gov/analogs/
https://www.nasa.gov/analogs/media
We got information about the Perseverance and Curiosity rovers such as the size of the wheels of these rovers, their weight and their characteristics in order to get an idea and repair the wheel of our rover that was broken. On the other hand, this information helped us to have a clear idea of what the conditions on Mars would be like with analog missions, as well as to know what tools astronauts need in missions of this type.
Hackathon Journey
The Space Apps experience was very good in many aspects, it was a learning activity, fun and at the same time it presented a challenge to each one of us. We learned about teamwork, networking, the importance of having groups with people from different disciplines and the contribution we can all give in a project. The knowledge we had and the way we managed to merge them inspired us to take this challenge, besides being something in which our colleagues were specialized, 3D. To solve the project we mostly took into account the well-being of the astronaut and how we could make him live well during the 1 year mission while maximizing and optimizing resources. On the other hand we made a schedule, analyzed the knowledge that each of us had and then we divided the jobs according to our skills. We would like to thank our mentor Joseph Joamy for all the advice and support he gave us throughout the competition.
