"Sloshy" is the best term I could come up with. This little fidget thing flexes, droops, rotates, and essentially numbs your mind for a few minutes. It's about 10 cm at regular size.

Printing this can be a little finicky. The walls are super thin at 100% size (1 mm thick!) so you might need to level your bed before trying this. But, what better way to motivate you to finally level your bed anyway, so it's all good.
You shouldn't use supports, and avoid brims if you can (they're an absolute pain to cut off). Scaling this up to be bigger shouldn't be a problem.
Depending on how good your printer is, the print quality could range from normal to extra detail. It's up to you to know what your printer can and can't handle.

The center part in the photos has been filled in, as it was poking fingers during use (it also adds some weight). If anyone would like an .f3d let me know.

i made this in pla using my creality 3 pro
