Flushing Volume Calibration Cube

I had issues with a model and the flushing volumes, so I was told to print a test cube with different colors on the top half of a cube. I couldn't find an easily paintable cube to test out these flushing volumes, so I put one together myself. I am still very young in my model engineering days - as is evident by the misalignments of the cubes here and there, but this should work to get the trick done… and you will be able to bucket fill a color on the sides, vs having to manually paint a cube to make this work. I have the scale set to 50%, to make it print faster and use less filament as you are just seeing what happens as you adjust your flushing volumes between different colors on here.
