AG3 - AG13 adapter
thingiverse
This simple adapter converts an AG3(LR41) battery to fit into an AG13(LR44) slot. Digital calipers and thermometers often use [AG13/LR44](https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/LR44_Button_Cell_Battery_IEC_Standard_Version.jpg/240px-LR44_Button_Cell_Battery_IEC_Standard_Version.jpg) batteries. Check the size specs at [List of battery sizes wiki](https://en.wikipedia.org/wiki/List_of_battery_sizes#Button_cells_-_coin,_watch). I printed this adapter because I have a lot of AG3 batteries, but no AG13 batteries on hand.
