This shows how an idea can be realized with the help of everyone with different technical skills.

Vase/tree pot was created using the python script found here http://www.thingiverse.com/thing:104694.
Tree trunk/base/connector designed in Solidworks. Trunk fits directly into base. Connector is required to join two trunks.
Tree leaves (small/medium/large), snowflakes and stars designed using SketchUp/Illustrator
Other dangling baubles were finger drawn using Doodle3D (http://doodle3d.com/)
Angel topping from http://www.thingiverse.com/thing:5049
Arduino NeoPixel (http://learn.adafruit.com/adafruit-neopixel-uberguide) for the lights

Print 3 trunks, 2 connectors, 5 small, 5 medium, 5 large, 1 base.
Each trunk fits 5 leaves. Connect 2 trunks with a connector. Connect trunk straight to base.

Print snowflake and stars as desired.
