Color changing LED ornament with BlinkM MinM

Thingiverse user GearsOfWow made this really neat 3d-printed LED ornament as a gift for his wife. It contains a BlinkM MinM with a CR123-sized 3V battery.

The entire project is just 50mm square, and most of that is because of the battery. For more details about it, check out the Thingiverse page about it.
