I created Arduino Uno Box when teaching the use of arduino in schools.
When a project was explained over several lessons, I had the problem of the time to dismantle the circuit at the end of the lesson, and some time to reassemble it at the beginning of the following lesson.
So I created a box that could hold Arduino Uno with a breadboard with a circuit mounted it.
The object is composed of:
1) A bottom to be able to contain some basic components
2) A base on which an Arduino UNO and a breadboard are fixed
3) A cover high enough to allow closing with a circuit mounted
4) Two hooks to tie or sew a 5mm wide elastic band to keep the box closed
