modular microcontroller and breadboard holder

This is a modular holder system compatible with an Arduino Nano, Arduino Uno, or ESP32. You can customize the setup by combining the microcontroller holder with the breadboard holder according to your needs. Simply connect the two modules as shown in the pictures. If the tolerances don't keep the holder in the desired angle, you can use a filament string, as demonstrated in the picture, or apply glue for extra stability. The microcontrollers are secured with M3 6mm screws. If you have a diff
