This tool is a screwdriver with interchangeable heads and a built-in LED light. The model includes a key chain ring, giving astronauts much easier accessibility. The current heads are mainly for concept, others could be modeled and printed. Research shows that screwdrivers and screwdriver heads take up whole kits and drawers on the ISS. Creating a screwdriver that already has multiple heads, saves space and volume because it will take up less room with the screwdriver heads already there.The built-in LED light takes up less room because astronauts won’t need to carry around whole flashlights because they’ll have light within the click of a button. The key chain ring makes it portable and gives astronauts quicker access. So this multi-functional screwdriver won’t need it’s own spot in a space drawer or kit. The interchangeable heads make using a screwdriver a much quicker and easier process because they already have other heads at their fingertips. Overall, this tool is very convenient.
