"Shapes" Don't Show to Print

This is embarrassing, but I ask because I've been unable to find the answer via the help and tutorials.

I've created a simple graphic - two concentric circles and an array of spokes.  The circles are in the base layer. I created each spoke as a "shape;" each resides in its own layer.  The spokes do not show in the print preview and of course, do not print.

I've attached some screen shots to better illustrate the situation. I'd appreciate any guidance on how to print what I have while retaining the ability to manipulate each spoke as a distinct entity.

The file is small (~3MB); I can provide it on request.
