ArduinoPlate v03 – compact, modular prototyping base

ArduinoPlate v03 is the new platform for Arduino UNO R3 and a breadboard: smaller, printable even on 180×180 mm beds, with a slide-in mount for the board and a snap-fit breadboard holder. I’m sharing the 3D-printing and laser-cutting sources so anyone can replicate and adapt it.
This platform was born from the daily need for a neat, reusable, and accessible work base for lab activities. After the v02—already used by several colleagues in other schools—I gathered feedback from students and teachers and designed v03: same philosophy, but even more practical.

At a glance

- Compact footprint (180×180 mm print bed)
- Slide-in mount for Arduino UNO R3 (no screws)
- Snap-fit breadboard enclosure
- 3D and laser-cut sources included

In some classes, assembly is a lab activity in its own right; that’s why I organized the steps in a sequential and complete way. To the more “maker-minded” readers: please don’t be surprised by the basic instructions—with younger students it’s essential not to ta
