Over the past few weeks my classmates and I have been working on the Mars Medical Challenge. I have learned many things while constructing my medical device. Some key things I have learned during this challenge consist of, knowing how to use a three dimensional printer, knowing how to create thing that come to mind, etc. My idea was to create a multi tool which consists of a tooth brush at one end and a comb on the other. Originally I was going to have a toothpick involved also but it did not work as planned. This would be a helpful device for astronauts because instead of having a separate brush and comb they are combined. This makes it less riskier to lose one of the objects and this also saves a lot of space. Overall I feel that my multi tool will truly help for a trip to Mars.
