technique to get multiple colors in the first layer with a single extruder. You'll need to import both files into your slicer to line them up manually then slice them separately. Then, you'll need to change colors on the second print for the pentagram.
Note: unlike the in the link above, the text here is 0.4mm thick, not 0.2mm. You'll need z-hop to be at least 0.5mm to avoid collisions.
If you don't won't the text on the back, use your slicer to lower pentagram_full.stl in the z-axis by 0.4mm and ignore the text pentagram_full_text.stl file.
