These are cases to hold spare batteries for Samsung Galaxy S4/S5 phone batteries. I created them because I was concerned about shorting out the batteries as I carried them in my pocket.
The Openscad files are parameterized so the can be easily modified to hold other batteries.
There is also an option to add initials using Openscad font
