This object, when combined with a music box insert from Music Box Attic, is an "A Clockwork Orange" themed orange that plays "Singing in the Rain" when wound up. The SCAD file included renders full color, with all parts in place. If necessary, you can edit the file to render each piece separately for single-color printing.

(Alternate source for mechanism)

Here's a video of an early version where only the base and hat were printed. The orange in this case was a styrofoam ball and the eye was painted on.

UPDATE: Added STL and SCAD files for separate printing.
