Long story short, I was challenged to 3d model and print a slinky from the pineapple under the sea model, you can see the video in the link below

This toy is really adictive, BambuLab PLA Matte was great and seems pretty flexible and durable, feel free to experiment with other materials.
I recommend not to change the scale since it will mess the spring and may be impossible to separate.
For any interest in using this model for commercial purposes, please get in touch here or in the instagram page.
