I wanted a connector for the Lego 9v system but the only way to get one was from overpriced vintage wires.

So, I designed this thing.
It is cheap and easy to make but it doesn't hold in place as well as original Lego connectors.

Any improvements or remixes are welcome, just credit me !

I used tree supports as they are quite easy to remove.
