Christmas Tree Topper Star Base

This is a base module that substitutes for one of the points in the excellent 12 point hanging star: http://www.thingiverse.com/thing:35866 and makes it a tree topper.

Parametric OpenSCAD file attached so you can customize for your tree or bulb. Docking pentagonal ring fits star as is. Vent holes double as branch tip slots. Bulb slot for single E27 LED spot. Tweak as needed.
