Milwaukee M12 Battery Holder

This design is by RB Tools and was found on Printables Under the "Creative Commons (4.0 International License) Attribution" License. The design was not modified. As I acquired more power tools, I ran into a problem. How am I going to store the batteries? As I was looking for an answer, I found that many people already solved this problem. This battery holder is for Milwaukee M12 batteries. Printables Link: https://www.printables.com/model/1262079-milwaukee-m12-battery-holder License: https://creativecommons.org/licenses/by/4.0/
