Ryobi One+ Adapter Connector

I just added negative & positive symbols to object. I liked the simplicity of this design and it gets the job done. I used the cover of an old 9volt battery for the metal strips. They were cut into 5mm strip with tin snips then sanded to remove the protected coating. The strips were then inserted and folded into place. The outer tabs were double folded for added strength and then inserted into some F connectors. Connectors were hot glued into place and any exposed metal was also hot glued over.
