Like the title says, post pictures of items that you've repurposed for your camera kit. These items are things that are meant to be used for other things/reasons that you thought "hey, this would do great for....<purpose/reason/object/etc..>". Please state the uses you put the item through, and why you included it as part of your kit.
I'll start off with:
This is actually the second time I've repurposed one of these neoprene 3ds/DS cases. The first time, I figured out that it was perfect for holding my Seagate 1tb USB 3.0 portable HDD. For my camera kit, I've repurposed one of these cases to hold my battery charger and a spare battery pack (it can hold more). It can also hold memory cards in those little plastic sd card holders in addition to the charger and battery packs. It's made of spandex covered spongy neoprene with a velcro closure, and has fake leather on the face. Thanks to this item, I don't have to dig for either the charger or the spare battery. I just load those objects into the case and slip it into the side pocket on my LowePro Adventura 170 and go.
