So I set this text to change the bottom layer to concentric only for the text and I got this. I had this large flat area in my print and decided to spice it up a bit for fun without doing multicolor which would be 1, too annoying to do manually and 2, too visible for this part that needs to be all black. So here I have a nice DON’T PANIC on the back of it.
Here’s a picture of the part assembled.
