This is a compact mini breadboard holder designed for the ESP32-C3 Supermini, created to make quick prototyping easier and cleaner.

The design allows you to reuse the metal rails from a standard breadboard. Simply remove the rails from a regular breadboard and insert them into the slots of this print. The ESP32-C3 sits on top, giving you accessible prototyping connections in a very small footprint.

The enclosure prints easily without supports and is assembled with a single M3x6mm flat head screw, which holds the top and bottom parts together while securing the rails in place.

Features
