Obtained in The Lab, the Squeeze Box is used by Atoi/Iota to suck things in and blow them out, in addition to granting the ability to change the environment to reach platforms, destroy scraps, move obstacles, etc. It was created by the Chief Scientist. The Squeeze Box is so incredibly powerful that it managed to damage the lab in a single hit, causing new Scraps to appear.
Tearaway says of the Squeeze Box:
"The work of the Lab's finest minds. Dispatch Scraps, turn turbines, fire projectiles...so many uses!"
