CR12xx Coin Battery Storage for Gridfinity
The next set in my Gridfinity Coin Battery Storage models.
Keep your tiny power cells from vanishing into the void with this Gridfinity-compatible CR12xx coin battery holder! Designed for CR1216, CR1220, and CR1225 sizes, each bin is precision-fitted to hold batteries securely without rattle or fuss. Whether you're a tinkerer, tech enthusiast, or just tired of mystery batteries rolling around your drawer, this compact storage system helps you sort, store, and grab exactly what you need—no coin flipping required. Designed with clear labeling, they’re practical and stylish in any workspace.
The Gridfinity bins in this collection sized for 1x1x3u and 1x3x3u, 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 do an alternate style for the 1x3x3u models. Still included are the ones with gaps between groups of batteries aligned with their Gridfinity bases, but also included are versions with just one looooong row of batteries, no gaps. Choose whichever appeals to you more.
This collection supports the following battery sizes:
Model Dimensions
CR1216 12.5 D 1.6 H
CR1220 12.5 D 2.0 H
CR1225 12.5 D 2.5 H
The filaments I used for the model pictured are SUNLU PLA Matte Gray and Elegoo Matte PLA Sunshine Yellow.
