My tool is a combination of a wrench and a flat head screw driver. It is small enough to be used in space, and really handy. The screw driver is very useful, because it can fix loose screws on the space station. Also, the wrench is useful because it can tighten or loosen bolts. I combined them so that they would have to print less. In addition, the combination makes it convenient to do a job that requires both a wrench and a screwdriver. Regular screw drivers or wrenches would be too big and bulky to carry everywhere. That is why they should be 3D printed. The name of my tool is the screw driving wrench.
