AA 2 D

The design has been updated to adopt a sleeve-and-contact separation structure. The contact module can move up and down, making it convenient to remove the battery. Additionally, the contact module can be reconfigured to accommodate different screw standards, ensuring compatibility with various screws. The current module uses M4x12cm screws.

The current model is provided as a single integrated file, which might lead to printing issues. For a more reliable printing experience, a complete set of separate parts is available on cults3d.com.
