Multi-Extrusion Alignment Test

This model is a Multi-Extrusion Alignment Test (MEAT). When you print it with dual-extrusion or triple-extrusion filament you can see how the colors are aligned with respect to the build plate so you can rotate your model in the slicer to get the colors facing the way you want on your model. There are lines and labels for the X and Y axes and marks at 22.5°, 45° and 67.5° within each quadrant to help you estimate the angle where the color transition occurs. The test piece has high walls so you can see the effect on both concave and convex surfaces. Slice the test using a layer height and infill that allow it to be printed as quickly as possible. Appropriate values might be 0.2 mm and 5%. Set the temperature and speed to match what you intend to use for your model.
