If like in my household, the thermoserver was put in the oven to keep warm, by people who will not be named, it will melt. This is a replacement for it. If you want a smoother finish to the top, print with the top facing up and use supports. If you have a nice clean bed to print on, then top of the lid facing down will need no supports, but the part of the lid that has the indent with the thumb indent will print better with the top facing up.
