A simple storage rack for holding 6 NP-FW50 battery packs for Sony APS-C mirrorless cameras. Hold batteries snugly, making it a good option for tossing into your camera bag without worrying about having batteries get lost or difficult to find when needed. The holes in the bottom allow you to push the battery out to easily remove it.

I printed mine from PETG with ~20% fill and it has held up great (at least 2 years of pretty heavy use). Additional helpful tidbit (at least for me), I put the batteries in with the leads down when they are full, and then rotate them with the leads exposed when they're depleted. It makes it quick and easy to identify which batteries are good to go when I need them.
