I needed a CR2450 battery, I only had a CR2032. This adapter lets you use the smaller batter in the larger clip. This only works with clips that take the positive voltage from the side of the battery, it wont work if it take it from the top.
The two batteries are the same voltage so you have wont have issues but the CR2032 wont last as long. Make sure to insert the battery with the negative side pointing outside of the case and line up the exposed side with the battery clip's reader.
Printed PLA, 0.2mm line height, letters down on the bed.
I included the SCAD file which requires BOSL2 to compile. It's got some magic numbers for this particular conversion but is modifiable for other battery sizes.
