So, first I would like to mention that I believe that because the battery "terminals" are recessed into the black plastic protector of our batteries, the contacts should be considered "covered". However, I can also see how a person could decide that a knife blade (something you should not have on your person while flying...) could wedge between the protectors. I have also downloaded and printed a few of the available protectors that just snap over this black plastic portion of our battery, and they can be easily knocked off....
So, I decided to see if I could design one that attached to the battery using the same clip that holds the battery to the body. The final design is no larger than the square footprint of the battery itself (exact for the bottom, by 2mm) so it still fits in my case no different than without the cover.
Let me know your thoughts.
For anyone who would like the file to print them yourself....I am happy to provide this. If you don't have a printer, and would like to have them printed, you can sent it to Shapeways, or you can contact a good friend of mine who said he would print them for 5.00 each, and ship them in a flat rate box in the USA at cost (you can get several in one box). His contact info is:

He did say I would be happy to investigate shipping to other countries.
