This is an insert for AA batteries, ideal for eneloops, NiMH, or any AA sized cell. Print the original box designed by @Flybo1116 then print this insert instead of the 18650 insert.
The battery "silos" are a little narrower and not quite so deep as the 18650 version, to better support AA cells. I added a pedestal at the bottom so ties don't disappear into a void. This keeps the insert the same size as the original 18650 insert so that they are interchangeable between identical boxes.
I also made the Fusion 360 CAD for the insert parametric (BatterySiloDiameter and BatterySiloDepth), so it will be easier to modify for other battery sizes. At some point I may rebuild the entire file from scratch to make it fully parametric, but the CAD file has been through a few hands and has some issues that would make it difficult to convert to a fully parametric design.
I used a piece of raw TPU filament in the top groove of the box, to give the lid that extras bit of "spring". This is optional.
