A 2x2x1 gridfinity module that holds 8 AA and 8 AAA rechargeable batteries with a compartment to store the splitter that comes with many different models such as the SMARTOOOLS USB-C ones in the image.
The hinge is just a length of unused filament which should be loose inside of the lid and friction fit into the sides of the container.
If you need to manually modify these holes in order for the filament to fit you can use a 2mm drill bit for the lid and you can also use a small length of filament in a drill to create the perfect friction fit diameter on the container. Yes, that's right, use some filament as the drill bit!
Printed at 0.2mm layer height with 20% Cubic infill in this case
