Glowda: the Glowing Yoda

Take your basic Yoda head and boolean punch an led and a 2032 lithium battery into the bottom and you get Glowda.

See http://www.thingiverse.com/thing:241887 for the boolean punch to make anything glow.

For best results print in yellow glow-in-the-dark and use a UV LED. That really makes Yoda pop with a cool radioactive glow.
