High-Level Project Summary
The habitat on Mars has been pre-constructed using robotic manufacturing techniques and indigenous (local) resources, such as Martian regolith (sand and rocks) and polymer materials made from the CO2 in the Martian atmosphere. Due a rough landing the most of the tools and spares are lost, and our rover are damaged. Our Target is generate all the parts, infrastructure and parts required to change succesfully the nerve of the wheel of the rover.

Detailed Project Description
Our habitat haven´t the dimensions and the surfaces to perform the reparation, so, we opted to print one room to use it as a workshop. The same has 3,5 m of length, 2,8m of width and 2 m of height, giving us almost 10 square meters for perform the operations.
Due the nature of the operations, it is not needed the pressurization of the environment, so It could be open and It doesn´t need any door and support life systems.
Together with the structure, a table and support libraries will be printed, making a monolithic structure, improving its resistance, and printing times.
The operation will consist in remove the highlighted screws, take out the wheel, remove the broken nerve, scan it for print a new one, and assembly all the components again. For this we will need a set of socket keys for the screws, and one spanner.
We will print in plastic the following box for contain every screw and part disassembled.
The box has the following dimensions
300mm x 100mm x 60mm
Due the lack of keys for the screws, we will recyclate metallic bars from the wreckages and we will manufacture handles for them.
The handles have the following dimensions
30 mm diameter x 80mm lenght
At the moment of the disassembly, we broke 4 screws, so we must print them in metal. They are 4x ISO 4762 M8 x 30mm.
Finally, we dismounted the nerv, wich has a dimension of 110mm x 40mm x 80mm and printed it in metal.

Hackathon Journey
We developed the solutions with a non-availability resources approach, using wreckages and the littlest amount of resources possible. It was wonderful use our knowledge in a real case, and how could we help to the science advance.
