Since I have the ESP32 and try to build circuits I have problems because I only have one free space left to connect to the standard breadboard. So I decided to make a version so that it's in the first column and free up space.
On the internet I did not find the connectors used in breadboards, so I disassembled one to use them.
The author remixed this model.
I made the gap in between larger, because for some reason my esp didn't fit in the original model
