Gridfinity Round Hygrometer Storage

I got a box of four round hygrometers (like these for example) and didn't want to keep four boxes around. Each one had a battery in it and also came with a spare battery. I have a bin for LR44 batteries, but since these things are just a bit too wide for a single gridfinity row, I used the extra space to store all the LR44 batteries that they came with.
