This is a decorative, hollow jack-o'-lantern that has been sized to be able to fit an LED tealight (fire and plastic don't mix, please don't put a real candle in this). You could also use it as a decorative container if that's your thing.
I printed this in PLA at 0.15mm on a 0.40mm nozzle. The 3MF file includes the support setup I went with (I'm sure it can be improved).
It's necessary to print with supports, though they can be a bit of a hassle to remove around the mouth.
Slicing can take a bit; I went a little nuts with the subdivision on this model. Sorry.
The author marked this model as their own original creation.
