This is a hollowed out pumpkin that you can digitally carve it yourself! If you upload to a cad software (I used Tinkercad) you should be able to carve it yourself. If you put a small light inside the pumpkin, like the flashlight on a cellphone, it should glow.
Update: I've flattened the bottom so that it will have slightly better buildplate adhesion without having to add a brim.
Polylite 2.85 PLA
Only have supports touching the build plate.
