This is a parametric model, so it is also possible to change the adapter to different sizes, as long as the dimensions are provided in the FreeCAD sheet.
The STL and Step file is made for two CR2025 batteries back to back with a strip of aluminum foil to make the unit two batteries in parallel: Keeping the voltage at 3V.
Important: A small piece of tape is added on the edge of the battery below the strip of aluminum foil to prevent accidental shorts, as noted in the screenshot. The aluminum foil is then held down with a small piece of tape.
