I wanted to replace the battery in my humidity sensor, but it turned out it required an LR1130. I only had LR44 batteries on hand (which are much thicker). To make them fit, I designed and printed this adapter with optional wire connections. Hopefully, it will be useful for someone else too.

For wiring: insert a stripped wire on each side of the slot—when the battery is placed, it will make contact with them.

Make sure to print it horizontally, so the layer lines run parallel to the battery surface—otherwise, the holder becomes very fragile. Don’t forget to enable tree supports.

You want to support me? Buy me a coffee :) Thanks!
