Tall print wobbling tester

I recently printed a couple of tall objects. I've noticed that the upper part of the object appeared gradually increasing wobbling, even if the bottom 10cm were perfect.
So, I designed this tall cylinder to print it in **vase mode** and so I can investigate the problem.

PS. This thing was made with Tinkercad. I love the random names it gives to the designs: Magnificent Tumelo-Jaban!
