This is a 23A Battery holder that is able to fit into a 15mm tube to make Cosplay props and other whatevers with. Enjoy!!! Print with support in fine resolution for the best results. I use 50% infill for strength because the battery has to be pushed in and out when replaced.
I would imagine that you could Remix this Thing into whatever battery cases are required, so I look forward to seeing all the other sizes so I don't have to do it LOL...
