Twist bottle

thingiverse

I'm inspired by Twist Vases, so I made it a bottle where you can put something inside. The customizer here only offers three shapes, but the twist_bottle module inside the source file is fully customizable. You can use your own shape to create a twist bottle as long as you center it at the origin. At 100mm high, I twisted the bottle just 180 degrees, but feel free to try more - like 270 degrees. The more twists, the better the visual effect, but they do affect how smooth the spiral goes down.
