Anybody know of a source for an upper grill that has a "honeycomb" pattern to it?

I'm looking to match the top grill texture with the lower two....

 

now that will be interesting to see

 

I've looked everywhere for it and can't find anything. I even went to a local plastics shop to see if they could make it and they said no (although I think they guy just didn't want to mess with it). If you find anything let me know.
