Flat Arc Reactor for Cosplay

This is my first OpenSCAD project. I wanted to make an Iron man arc reactor that could be worn. Next task is to make it print friendly by separating the various parts.
Note that the coil guides have been designed to have real wire wrapped around them to improve the realism.
OpenSCAD code is also in GitHub here:

The holes are for fitting LEDs and the channels are for the wires.
