Celestron AVX Bubble Level

The original upload by [bowiesjustaknife](https://www.thingiverse.com/bowiesjustaknife) was a .step file of the base including a representation of the the bubble level, so no good for slicing/printing with Cura etc,

UPDATE: [bowiesjustaknife](https://www.thingiverse.com/bowiesjustaknife) has finally uploaded a proper STL, minus the bubble level, in April 2024 to his original design.
Not sure if it takes into account the extra thickness issue mentioned below.

2 files included:
AVX_Bubble_Level.stl: This is just the base part with the bubble level removed, in STL format.
AVX_Bubble_Level - THICKER.stl: When I printed the original, it rocked slightly on the threaded bolt, so I made this version to be a better fit.

All credit to [bowiesjustaknife](https://www.thingiverse.com/bowiesjustaknife) for the actual design
