Could use some help. I'm trying to find a AAA single battery cover/case for my flashlight and you would think that would be easy but it's not. I am looking for something just as slender as the battery not like a double case or anything for carry but I can't find anything from Google to AliExpress to eBay. The only remote thing I could find was countycomm's battery locker (pic related) but fuck paying $20 bucks. Any ideas?
