Pass through cylinders (set of six STL pairs)

I developed a simple program that creates a pass through cylinders from text or pictures. Now I print these spirals and can't stop)

I will be glad if you like these 6 spiral cylinders.

You can download my program and also create any pass through. It's easy!
