V393 to V303 Button Cell Adapter

The battery in my calipers (V303 size) was about to die... but I had no suitable replacement at hand. I did have a box of smaller button cells (V393) that no-one was using anymore. All I had to do was make something to fill in the extra space and keep the smaller battery pressed against the side and bottom contacts. A simple crescent should do!
