SKNI TOOL
High-Level Project Summary
This is our solution for challange: Outfitting a Mars Habitat: A 3D Print ChallengeWe have developed a useful multi-purpose tool and a wheel model for a martian rover.Our multi-tool product allows user to save resources needed to create tools with similiar abilites.

Detailed Project Description
The multi-tool is a device similar to the swiss pocket knife for an astronaut. It posesses embedded features like flat wrenches and screwdrivers with multiple diverse bits. Moreover this basic tool can be extended with additional modules, one of which is an extension bar which allows for more leverage, often necessary to unscrew a hard stuck bolt. Furthermore this very simple design allows for more modules to be designed, as needed in future research.
The main advantage of this multitool is its ergonomy and universality combined with low cost and mostly negligable weight. This is noticable especially when compared to other alternative approaches such as an universal toolset which usually contains many more elements, at a cost of bulkier dimensions and much higher weight.
Such tool could also find usage outside of a marsian habitat. Because of its small size, one could easily take it to the camping or even longer journey. What is more it could also be used to service a bike or perform simple house repairs.
Following tools were used during the development process: Tinkercad, Blender, Powerpoint, PrusaSlicer, 3D printer Prusa MK3S+.
Another project realized during this hackaton is a replacement wheel for the martian rover. Because of limited size of available 3D printers, it was not possible to print it in a single piece. Instead we decided to redesign it, based on already available photos of Curiosity and Perserverance rovers' wheels.
We have divided the wheel into center hub, "S" shaped springs used to connect it with outer threadwear and 12 threadwear pieces. Each outer piece is held to the center hub by a single spring, which allows for independent suspension and, in the case of a malfunction, replacement of a single element. We have also designed a special plate, which when installed instead of normal threadwear segment allows for optical tracking of distance crossed by the rover.
We have also decided to improve the original design by adding special outer plates, that shields inner side of the wheel - springs and the center hub - from rocks and other debris coming from the outside side of the rover. Such shield on the closer wheel side would be more complex, since this is also the place where engine is placed. Instead we have added a litlle bent edge that makes it harder for sand and small rocks to enter and later accumulate inside of the wheel.

Our inspiration for creating multi-tool was: https://nasa3d.arc.nasa.gov/detail/mpmt
Moreover we learnd about Mars from : https://www.youtube.com/watch?v=SwFcwEBIiEQ&feature=youtu.be
To create rover wheel model we took these models:

Hackathon Journey
Our team is not expirienced with 3D printing nor designing tools or mechanisms.
During the challange we have learned a lot about creating 3D models and printing in plastic.
We had a pleasure to meet amazing people with outstanding experience and knowledge.
