Happy Happy Rainbow

Having acquired enough filament colors to do a rainbow, I designed a two piece Happy Happy Rainbow. The rainbow itself was printed with 0.25mm level heights, with the g-code manually modified more or less per Modified_Gemini's instructions at http://www.thingiverse.com/thing:2044713. No supports were necessary.

The PLA in the rainbow is best removed promptly from the heated bed and then held in the arch position to cool- it actually holds its shape quite well by itself when cooled. I sanded the elephant-foot edges of the happy face to ease the fit. The base of the happy face could use some modification to make it more stable.
