fidget spirals

A collection of different nice print-in-place spirals. While the smaller ones fit in your pocket/hand the bigger and dangerous ones are more useful for educational/decorative usage. These models are good examples on science being eternal and are also useful to show the huge difference between 3D printer nozzle sizes. The sizes are 5 - 10 - 20 cm in diameter.

Printing

Even watching the printer while printing these spirals troubles some people ("vertigo"). Print with the highest temperature your filament likes to have. Even stringy filaments will print without strings, that's part of the magic.

Vertigo

Benign paroxysmal positional vertigo
