Atom 3.1 missing lens protector?

I just purchased a new Atom 3.1 and it came with the stick-on lens screen but not the plastic/rubberized lens protector that slips over the computer and buttons. I know this came with the older versions of the Atom computers - what happened? At the price of these computers there is no excuse to include a $5 lens cover, yet I cannot even seem to find one to purchase separately. Will the covers from the Aeris line work (the Freedive series case looks very similar to the Atom)? Any help?

Thanks!
