Bort is in!
So hard to choose a colour, though probably not orange since the 18650 holders i use (repurposed match holders) are orange so differentiation is a good idea.
Maybe red, thats always a solid colour.

Thanks but I think it would be great to let someone else try out one of your cases

@spicy3d Battery Storage Boxes | Spicy 3D Prints ) a little hole in the bottom?
That way you can turn a holder sideways and test all batteries with a multimeter without taking every battery out and in again.

Have your battery holders (this ones Battery Storage Boxes | Spicy 3D Prints ) a little hole in the bottom?

That is a good idea! The bottom of the battery boxes is presently solid (no hole).
I have been thinking about adding a feature that holds the batteries in place even when the battery box is upside down. I’m not sure yet what would the best retention mechanism would be though.

You could also put a groove down the middle for battery placement for testing.

well, the layers are in the wrong orientation for a vertical spring.
or the spring design from a holder
For my electronic projects I often need battery holders of various size and for different number of cells: single, multiple cells in parallel or in series, or serial lithium-ion type cells with connectors for balanced charging between the cells. ...
