USB Chargeable AA Battery Holder WIP (Gridfinity)

I recently purchased some AA batteries with USB-C ports for charging and I wanted a convenient place to store them. I figured it would be a good idea to have slots on the side so I could access the charging parts while they are stored. I made the design gridfinity compatible as I intent to set up a system in my desk when I get around to it.

I have included a step file as I hate converting stl files to make edits in CAD software, I assume others out there feel the same way.
