Printing and Assembly Guidance
For the shell, use 3-4 perimeters to prevent joystick screw holes from stripping. The main body may require tree supports for the joystick cutouts. For wiring, using a small piece of protoboard is recommended to centralize the Ground and VCC rails for the LCD and joysticks.
