It used to be only created through yaml but they recently added it configurable through UI. I have had my basement dehumidifier using one for about 3 years.
Just a warning be sure to give yourself at least a 30min run time and a long enough time between runs to let the coils warm up.
Too short of run time will burn up the compressor and too short of off time will freeze the coils and ice will build up.
Maybe but it looks like the highest point of the pumpkin flesh is higher than the lowest point of the stem so it wouldn’t look as good. This way is much less waste and faster because you can print all the stems at once.
