Use brim, no supports required. 

A large slinky-style fidget toy designed for stretching, compressing, bending, shaking, and general sensory interaction.

The toy measures approximately 175 mm in compressed height, but can be extended to more than 3 meters in length. Its flexible spiral structure allows movement in all directions while maintaining a lightweight and satisfying spring-like behavior.

After printing, the individual spiral layers need to be separated from each other manually. In most cases this can be done by hand. If some sections are fused more strongly together, a thin spatula or similar flat tool can help carefully separate the layers.
