CR20xx Coin Battery Storage for Gridfinity
Organize your coin batteries with this set of Gridfinity-compatible storage trays designed for CR20xx series batteries! This collection includes models tailored specifically for CR2032, CR2025, and CR2016 batteries, ensuring a snug and secure fit. Each tray is optimized for easy stacking and modular use with other Gridfinity systems, keeping your workshop neat and efficient. Whether you’re managing spare batteries for remotes, key fobs, or electronics projects, these holders will keep them safe and accessible. Designed with clear labeling and smooth battery slots, they’re practical and stylish in any workspace.
Updated May 29 2025 with support for four additional battery types.
I've added 1x1x3u and 1x3x3u designs for CR2012, CR2020, CR2040 and CR2050 battery types. Download either the 3MF (for AMS painted versions) or the individual STL files.
One of my favorite Gridfinity storage systems is "Slim Parts Storage" by Alcia Alford (link below). I got a bit carried away with it and printed more boxes than I needed. So I started looking around for something... Aha! Coin batteries!
But there was a problem. The Slim Parts Storage boxes are designed for 3u tall Gridfinity boxes, and the existing battery storage models I found - especially for the CR2032 and similar 20mm diameter batteries, were all taller than 3u and wouldn't fit. So I made my own, as one does.
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.
Currently it supports the following battery sizes:
Model Dimensions
CR2012 20.0 d 1.2 h
CR2016 20.0 d 1.6 h
CR2020 20.0 d 2.0 h
CR2025 20.0 d 2.5 h
CR2032 20.0 d 3.1 h
CR2040 20.0 d 4.0 h
CR2050 20.0 d 5.0 h
The filaments I used for the model pictured are SUNLU PLA Matte Gray, Bambu Lab PLA Matte Mandarin Orange, and Polymaker PLA Matte Pastel Banana.
