No, but I've used similar services before for rapid prototyping.

Unfortunately there is no easy way to do this, as they will be expecting a 
triangle mesh.  There are macros for POV lying around that will convert your 
CSG into a mesh, you might then want to import into a mesh modeller to check 
and tidy up any items.

I would also ask (or maybe it's on their website?) what resolution they work 
at.  This will determine the resolution of triangle mesh you want to 
generate from the CSG.

Given the simplicity of the model (and that several parts seem to be 
repeated), it might turn out faster in the end (and provide higher quality 
results) if you start again in a mesh modeller (or CAD software if you have 
access) rather than POV.
