My idea for the ISS Two for the Crew challenge is a mix between a wrench and a screwdriver, also called the wrench-driver. The average wrench can range in sizes while being able to screw only about one size bolt per wrench. But with the wrench-driver you can screw in three different sized bolts with one tool, there’s a small medium and large so there is no need for the 3 different wrenches when you can do it all in one tool. But there's more, one the other side is a screwdriver. Now this would be useful on the ISS because imagine you need to unscrew something on the wall to move it so you grab a screwdriver, but wait it’s bolted on, so then you have to float all the way back to get the wrench. But if you combine the two which I have done, you won’t have that issue and you won’t have those three extra wrenches taking up space. So this invention of mine, I believe I could save the astronauts both a lot of time, and some space in space. Please consider my invention to be sent to space.
