Victorian Hurricane Lamp

I have designed a 3D model of a Victorian style hurricane lamp. It holds a small battery-powered tea light. It comes in a number of pieces and screws together. Depending on which pieces you use, the lamp can be tall (26cm if you use all the pieces) or shorter with a combination as shown in the gallery. Tea lights used should not exceed 4cm in diameter. This is part of an experiment for myself to show that Blender can be used for models that require some precision work. The threads were built in OpenSCAD using the library by aubenc(http://www.thingiverse.com/thing:8796), but the assembly and design was done in Blender alone,importing the threads when needed. This model was also designed to push my printers further regarding clarity and overhang. None of the pieces require support to print.
