This project is designed for users who combine Sonoff Basics with regular light switches to create an affordable smart Wi-Fi switch.

I successfully printed out the design and it perfectly fits my Sonoff Basic. Although there are various revisions of this model, I believe it would work with newer versions as well. However, I haven't tested its compatibility with electrical boxes yet, but I don't see any reason why it wouldn't fit. Please take necessary precautions when working with high voltage, and use this project at your own risk.

To make it work, I had to trim down the built-in button slightly. Additionally, ensure that the ground wire doesn't cause any short circuits.
