I grew up watching Transformers and Thundercats. Now that the new shows have linked my past with my kids, I thought I would have a little fun an replace the emblem. Made for an older model Subaru Outback, but I am sure it can be resized for other applications. I do not currently have a dual extruder set up yet. Slice STL as you normally would. Cut STL into two parts - First part would be around Layer 5 (if sliced at .2mm) When first file finishes, swap out filament, prime like crazy to make sure the red does not bleed into the black, print second file. You can also put in a pause command and reset to 0,0, but I was not sure how to set the pause to only resume when I triggered it to.
