About this 3D model
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 "Approximately 2.4% of people are affected at some point in time."
