Gridfinity 2x1 Multi-Size Coin Cell Battery Holder (CR20xx / CR24xx / CR16xx / LR44 / 4LR44)

I had a growing pile of loose coin and button cells rolling around in drawers, so I designed this tidy little organiser to keep everything together.

The model is compact, prints without supports, and has individual columns sized just right so the batteries slide in easily but won’t tip out.
I’ve also included the Fusion360 file so you can customise things.
