Ghostly Glow LED Mushroom

Glowing mushroom for your desktop that is powered by any colored LED and batteries(or usb).
The legend says that:

• Green mushrooms are magical
• Blue mushrooms are ghostly
• Red mushrooms are poisonous / viking fuel ( http://en.wikipedia.org/wiki/Amanita_muscaria )
  Designed to be printed with PLA and to fit 2x 2032 lithium 3v batteries, a switch, led and a resistor. The leg of the mushroom is hollowed (3mm) for the wires and the resistor.
  Batteries are neatly hidden under the base. Switch is behind the base.
  Works ok as a ornament when printed with nontransparent plastic.
  (as a side idea the glow was to be produced with a UV led and with a glow in the dark plastic..could still work)
