Button battery adapter for watches

I found out that despite having big stockpile of button batteries, i never had the one i needed for my watch. So i made an adapter.

Button batteries have a lot of names for the same thing. Better look them up.
https://en.wikipedia.org/wiki/List_of_battery_sizes

files explained:

ag3 will allow [SR41, AG3, SR736] to fit in place designed for [SR45, AG9, SR936SW]
ag4 will allow [SR66, AG4, SR626] to fit in place designed for [SR57, AG7, SR927SW]

There are 2 variants of each adapter, as shown in photos:
-cutout in the center
-cutout in the side

Check which you need before printing, or print both just in case.

I'm not responsible for any equipment damage because you installed wrong battery, or shorts caused by the adapter coming loose. You use these at your own risk.
