BreadBoard Extension for ESP32 or else

This little Gadget expands 2 "normal" MB-102 Breadboards with the space its needs for a perfect fit of an ESP32 Wroom Board or else.
The MB-102 is a middle-size Breadboard with 830 contacts and is available with a power supply adapter...
I'm adding the OpenScad file also, so you can easily adapt this rail for other boards.
I hope you enjoy this little helper !
kind regards, Frank
