The 3D model I have created is a mixture of three different screwdrivers, the plus head, the flathead, and a hexagonal head and I call it The Triple Header. The flathead is on the left side, the hexagonal head is on the right side, and the plus head is poking out of the center. The different heads are all at the end of cylinders. The cylinders are all connected with a rectangular prism . The total length is around eleven centimeters, the width is around six centimeters, and the height is around 1.5 centimeters. On the ISS the crew members will often use simple tools like hammers, wrenches, and screwdrivers. Aboard the space station the crew will have to screw in objects, so they can stay in place or keep together. It will be much easier for an ISS member to have one screwdriver with multiple heads, rather than multiple screwdrivers.
