Wavy Vase

thingiverse

Simple decorative piece. Or window treatments. Or just a base. As you spin a duplicate 90 degrees, the edge aligns perfectly with the adjacent vase. You can create intricate patterns by combining them. Even when scaled in depth, it still works seamlessly. Print at vase mode settings. Scale to your liking. Cut anywhere along its length, and it will still match the next identical piece (if it's a clone with matching dimensions).
