To commemorate the national title I drafted this banner to be printed in three colors.

Best to load up the 3MF file. You can then select each of the color groups in the slicer to color the file.

NOTE: The colors are not layered so cannot color by layer height. A future draft may include that.

Total height of the model is 1.2 mm. If you want a stiffer sign, scale up the z-axis to 1.6mm+.
