These battery contact plates are designed for DIY electronics projects where standard battery holders are not suitable or available.

The design allows you to wrap copper wire around the contact points to create a spring-loaded electrical connection. This provides flexibility and makes the parts easy to customize or repair.

Printing instructions (important):
Print the negative (-) plate in an upright position so that the FDM layer lines run along the direction of the spring. This significantly improves strength and prevents the spring section from snapping during use.
