I needed a smallish (e.g. 80 mm high) set of illuminated pumpkins to be carried around on wagon of a 1/32 (i.e. garden) scale model railway for a Halloween display.

The original scanned pumpkin was simplified, made into a hollow object and then formed into a lid for one of these:

...which holds a CR2032 battery and an orange "fire effect" LED.
