Calculator Case

There are 2 parts: the container (top) and slider (bottom). The container holds the Arduino and battery on the left side and the breadboard on the right side. "Kellkulator" is embossed on the top right corner. Below it is a rectangular hole so that the user can see the LCD screen inside. The 16 holes in the middle are for my 3D printed buttons to stick out. On the left face, the left rectangular hole is for the USB connector port on the Arduino to fit in and the right rectangular hole is for the DC barrel plug, so that I can easily upload code through the USB cable or connect the battery to the Arduino even with the container on. The rectangular slit above the right hole is for the wires that connect to the battery, which is hidden inside on top of the Arduino. On the inside of the container, a short wall forms a battery compartment. The left side of the container is shorter and cylindrical cuts were made on the inside of the front and back sides so that the slider part can slide in and complete the case.
