AAA Battery Case for Maker's Beginner Kit

So, I had a few ideas to make with the Maker's Beginner Kit, but the battery case that is provided to download for the kit is too wide with having all the batteries side by side, so I needed to redesign my own version which was longer and thinner and came up with this version. Although it still needs adapting for the designs I have in mind, it is in a finished state to be uploaded here. Hopefully it will be useful to someone else as well. Any issues give me a shout and I'll update the design. If you feel like giving me a boost it would be most appreciated. Thanks so much.
