Before reaching the current working prototype, I went through multiple enclosure iterations to test the overall shape, grip feel, joystick position, button placement, wall thickness, internal space, and assembly method.

The early white shells were mainly used to quickly check the basic form factor and how the device would feel in hand. Later versions moved closer to the current black prototype, with improved component placement, a more compact body, and better access for the joystick, buttons, display, NFC area, and internal electronics.
