I designed and 3D printed this modular electronics sorter for teaching purposes.

The box provides a dedicated slot for a MB102 breadboard and a 9V battery power supply module, making it perfect for quick prototyping and classroom use.

The lower compartments are divided into multiple sections to store:

Jumper wires (straight and pre-bent)

Resistors, capacitors, switches

Integrated circuits (ICs)

Arduino Nano or other small microcontroller boards

The layout keeps all essential components in one compact box, reducing clutter and making it easy for students to grab the parts they need.

If you want to stack sorters, print 4legs and glue them to the sorter. I used Loctite 401 for that.
