For this challenge I created the squishermizer 2000. This device is a sphere with finger dividers to make it more comfortable for hands. This is a device to help astronauts keep muscle strength that can be lost due to the conditions in space. But this also can be used as a stress ball, so astronauts will be able to relieve stress. When this is printed it should be printed out of polyamide and should be filled with one cup of cornstarch and a half cup of water. Once the mixture is stirred place it through the opening in the ball. This substance is hard when squished (for muscle strengthening purposes) but flowy when released (for stress relieving purposes).
