Description
A really simple squeeze toy, like a stress ball but designed to be easily printable with flexible filaments, specifically of Shore hardness 85a. There are no supports necessary, there's no bridging, and there are no overhangs beyond 45 degrees (except for a slight filet at the bottom).

Notes:
I printed this with a 0.4mm nozzle, 0.2 layer height, and 0.48mm line width.
I used 5% Gyroid infill and 3 walls, but you can tweak these settings to make the model more or less stiff. See Post-Printing for one more detail about stiffness.Printing the model as is will result in analmost air tight object, which makes fully squeezing it take a bit of effort, and makes it slow for the object to regain its shape afterwards.
If you'd like, this can be remedied by slicing off the top tip of the object to open up a small hole to let air pass in/out more easily.
