My tool is has a C shaped center with two bars on each side. Each bar has two stubs close to the edge to help hold things. The C in the middle is used to hold wires and keep them in one place. The bars with the stubs are for holding tools and items in place. The reason I chose this design is that wires on the shuttle could get tangled and messed up. So now astronauts can keep some of them in one place. The bars will keep tools in place when astronauts are working on the wires or something else. Also thanks to the stubs on the end of the bars, when the astronauts are working, the tools won’t fall out. This tool is also very simple to make and doesn’t use up a lot of materials. This tool also doesn’t take up much space.
