A pair of travel battery cases to hold either 4 AA or 6 AAA batteries. These cases do not use traditional threads. Instead, I have used a 6-start short thread for faster opening and closing.
awesome Container with very nice Touch and feel to the outside. I think the Container could Hold Up one battery more rather than 4 AA or 5 AAA...otherwise great and easy print...for me having spare batteries for the emergency is very neat
