This is a Thomas the Train pumpkin, designed to have a 50-52mm light installed in the Thomas head (a spirit of Halloween pumpkin light specifically). A light under the pumpkin works fine too. This also works with any printer with a 140mmx140mm build volume and here are my print settings: Layer height: 0.2-0.3mm, any speed and 10 percent infill.

How to install light: Under the pumpkin and behind the head, there is this slot where you can put the light (showed in 3rd image). Make sure the light is facing the head so the light shines through the eyes.
