I recently found this off airsplat. I think it's out of stock right now, since I cant find it off their website unless i do a google search. It's designed for the MB02, which should work on the MB03, and hopefully your TSD as well. Best part about it, is that it's cheap and apparently it's a metal enclosure design. Let me know what you think. Great post btw.
