I needed a simple battery holder for my 18650's. Most of the designs I saw were very small, so I made a very simple modification.
There are two files, one is the original and the second file is labeled #2. The second file features slightly larger outer walls, this is because it did not want to print correctly with the very thin walls of the original file it was remixed from. I would recommend the second version of the part file as it creates a much sturdier print.
