A very simple remix of @scampbell's fabulous grumpy pumpkin ("grumpkin"). I pulled the original flat-bottomed model into Meshmixer to hollow out the center for two different sizes of LED light. The smaller uses a

Lovefish LED tea candle

which is small, cheap, and just bright enough. The larger uses a

Soondar 10-LED Vase Base

which produces a ton of light in adjustable colors, making for some cool effects with both the face and the infill.(LINKS NOTE: I am not an Amazon affiliate, and receive no remuneration if you buy through those links.

The smaller grumpkin uses a domed cavity, while the larger uses a conical top to allow better light penetration toward the top. For the finished product, I had by daughter airbrush the stems a deep green.

Post-Printing

There's no required post processing, but you can optionally tape off the stem (@scampbell's model has a lovely little ridge that makes this easy) and paint it green.
