A quick to print and neat way to keep batteries together.

There are two versions, the inline "chain" version and an alternate "8-pack" version for a more compact solution.

The sizes are based off the AmazonBasics™ rechargeable batteries I have but you should be able to scale the model in your slicing software to suit your batteries.

If you want a simple way to ensure it'll hold your batteries then scale the model down a bit and cut each loop with some wire cutters, this will allow them to flex open and grip the batteries.

P.S. If you want another size please let me know and I'll make another .stl
