It's inspired by
Twist Vases
. I made it a bottle so that you may put something into it.
The customizer here provides only three shapes; howeve...r, the twist_bottle module inside the source file is generalized. You can use your own shape to create a twist bottle. The only thing should be noted is centering your shape at the origin.
At the height of 100mm, I only twist the bottle 180 degrees. You may try more degrees, such as 270 degrees. Twisting more will get more visual effects but affects the smoothness of spiraling down.
