I am spending a lot of time with development coin battery powered devices.

I have a full desk of batteries, and I've tried to solve this mess with a 3D printed battery holder. It's good for organization, but after time I see that it is just a dust collector. If I need to charge the batteries, this causes chaos. I used some USB hubs, and then I have a desk full of cables and chargers.

Here is a solution for charging and storage coin cell batteryes
