So I would like to know if someone knows a way to take this object https://www.thingiverse.com/thing:2539276 - and fill in the letters to make a custom inlay of them. I printed this coaster out in black. I would like to fill in the letters in orange. I just don't know how to extract the shapes to print out just the inlay portions. Don't really want someone to do it for me as much as pointing me in the right direction to be able to do it myself. thanks.
