LR41/SR41 & LR44/SR44 Battery Storage for Gridfinity
Another entry to my Gridfinity Battery Storage model series.
Updated 2026-01-05
I have added STL files and a 3MF print profile files for these models with the SR41 / SR44 text to go along with the LR41 / LR44 versions. Thank you to @ptr3960 for the suggestion!

The STL and 3MF files have been updated to include LR41/SR41 size batteries. Thank you to @knopster for the suggestion!
If you've got a set of digital calipers, odds are it uses LR44 batteries. So here, to go along with your other Gridfinity battery bins, are a couple of models for storing them! Designed with clear labeling, they’re practical and stylish in any workspace.
The Gridfinity bins in this collection are sized for 1x1x3u and 1x2x3u Gridfinity units, and are stackable even when loaded with batteries! These models have been 'painted' for use with an AMS, but of course will print fine in single-color setups as well.
Because these batteries have a smaller diameter than the previous collections I've done, I was able to arrange them a bit differently. The 1x1 model holds up to 6 batteries, while the 1x2 model will accommodate as many as 15. I know I could have fit a few more in there, but it started to mess up the aesthetics. And if you're printing these, you care how things look as well as how they work.
This collection supports the following battery size:
Model - Dimensions
SR41 / LR41 - 7.9 D 3.6 H
SR44 / LR44 - 11.6 D 5.4 H
The filaments I used for the models pictured are Sunlu Matte PLA Gray and Sunlu Matte PLA Powder Blue, and Sunlu PLA Bright Yellow.
