Logo of SolidWorks

thingiverse

The logo of SolidWorks. Change the filament for 1 millimeter height red at 1mm, for 1.2 millimeter black at 1.2mm, and again for 1.3 millimeter red at 1.3mm. Print with a 0.1 layer height or increase the z-scale to achieve a single layer of black. Only use one color of red; the color difference is made possible by the black layer. If your printer has Marlin firmware, you can change the filament by modifying your g-code and adding the line M600 before the affected layer.
