Breadboard Power Connector

This is to create a connector for the power rails in breadboards. It uses common pin headers, but this 3d printed part helps having something to pull the connector easier than just having the pins by itself.

For my case, I decided to have banana plugs in the other side so I can connect to my power supply, but you could add your own type of connector.

To assemble, solder the two wires into each row in the pin headers. Leave space in the center so it can fit inside the 3D print case. Use some kind of glue to keep everything together. I recommend epoxy: https://a.co/d/dv5bFJO

The small 3D printed part is like a cap to keep everything tight and with the wires supported. It's designed for 22 AWG wires.
