Portable Battery Caddy

Always loved the Storacell Caddy, but it's hard to get it where I am from. Finally managed to sketch one up myself. For rechargeable batteries, it will fit nicely without a magnet. For non-rechargeable ones, it's a little smaller in diameter. So, to make one size fit all, I added an 8x3mm magnet at the bottom. Hope anyone without access to Storacell can enjoy this!
