The ergo-wrench is a wrench that has many features. The clip on the top allows an astronaut to clip the wrench to surfaces in space because there is no gravity. It also has a cup to hold nuts and bolts with a slot that can hold a magnet so the items inside won’t float away. You can easily change the wrench’s size using the tool in CAD that allows you to change an item’s size. I came up with this idea when seeing that wrench’s were a tool commonly used in space and thought of a way to make carrying it easier.
