Is there a script that i haven't found That allows for Mass obj export to separate files?

I need something that will allow me to export every combined poly object to a separate obj file with the file named what the part is named in the scene.

Preferably it would be setup so that it worked not on the overall file, but an export selected option

Example i have a ship I've modeled it up and the parts are laid out like " Ship Hull" ..."ShipGun"..."Ship cockpit"

So forth and so on.

I want to be able to select the parts, click a mel or python button and have each one export as obj to a folder i specify with the file named the same as the Combined poly object is named.

When i get ready to Take a model form Maya into magics, i have to export each individual part of the file needed as a separate part in magics, ( magics takes every file you pull into it and creates it as a single part) To a new separate file. I cannot export strait to STL because Maya has some strange issue that causes a direct export to get all wonky with the size of the part, even after history is deleted, transforms are frozen, what ever. cannot figure out a way around it other then to Export the parts to obj, then export that to STL file. So, when i have to export 40-50 files or more for a model to be prototyped, a mass export script would be killer. Even better if i could select the file type, allowing me to import all the obj files into a single scene, and redo the mass export with the stl file type selected.
