Good case for 10s3p 36V pack ?

I wonder if there are any good case available to protect a simple 10s3p battery pack. Honeycomb or square design - doesn't matter. I've been looking for ages, and all I can find is that cheap kettle bottle battery design, which is really huge. I'm no fan of saddle / frame bags, because they tend to disappear rather quickly where I live, so If any of you knows a good hardcover case, feel free to share it!
