About this 3D model

For my projects I often need a battery holder that can be easily modified and multiplied, it is not difficult to print and it is quick to print. This is how I made this battery holder for AA batteries and the metal part is simply a paper clip. The support is provided with grooves for the clip, so the clip stays in place even after removing the battery. PS:The STEP file is included so it can be modified for any type of battery.
