4 Post Retraction Test

I really liked printing the cube for testing my final retraction tests made by [orionwnix](https://www.thingiverse.com/thing:16510) because I get to see the retraction settings impact in each direction.

...but I thought, "why just use the cube for my final test? Why not make it the actual test?" So I remixed the cube to be used with post processing scripts to change my retraction settings every level. Now I can test different retraction settings on the same cube.

The base is 2mm (10 layers at 0.2mm layer height) and each stage is 6mm high (30 layers at 0.2mm)

There are two versions. One with 5 sections for testing and one higher with 6 sections. Each labeled with a number.
