Spirit Level

In this exercise, you are given an assembly of a spirit level base and tube, with a loose ball for a float bubble.

Your task is to modify the assembly so that the bubble would always "float" to the top no matter what position the spirit level base is set at.

There is a parameter set up for modifying the base angle, and note that the rotation axis is not through the center of the tube swept radius.
