Make sure you print with Arachne mode on as it has thin walls to grip the battery.

I needed a LR41 but I only had LR60 batteries.
I made this adapter parametric, so you just need to put in 4 dimensions:

Larger battery diameter & height
Smaller battery diameter & height

You can use the table I added as a photo here that I found on Google images. Put in the dimensions as-is, I have offsets in seperately.

You may need to adjust the offset size to increase the side hole if you are adapting a very small battery to a very large battery.

This adapter works on devices where there is a side terminal and a bottom terminal. If you have a device with top and bottom connectors it won't work, as the battery would need to be thicker. You could try remove the top side and add some aluminium foil but I didn't have a need for it with my device. (I added an example picture of the thermometer I used it in)
