This is a 9V battery and wire connector-designed for use with breadboards,connectors and any other compatible electronics. It prints altogether in less then an hour,uses less than 10g of filament and is designed so YOU can keep on making your projects without any fuss. The files also contain an addon,which i recommend using for Dupont wires with circular or square bottoms,which help with stabilitty and make it easier to mount,which is one of the things I added to make life easier,along with +/- indicators on the sides so you can tell which is which by touch. if you encounter any issues with the model,let me know.
