T-FAB is a smartphone case made for play exclusively Tetris on your phone. It is for those nostalgic people that loved to play Tetris on their Gameboy, or for the ones that never got the chance to have one. 

The case is made from two main pieces of wood. The bottom part, milled with the CNC machine, has an exclusive pocket where you can put your phone, the top part is where the interface is. The top part is made out of plywood, and it is entirely cutted and engraved with the laser machine. It has a display window, an audio output, and five holes for the main buttons: left, right, down, “A” and Start button. 

Connected by magnets the top and the bottom are very easy to combine. The buttons are made with the 3D printer and are connected to the top with double-sided tape. Copper tape and screws are used to make contact with the smartphone.

The case is very similar and tries to mimic the original one. The interface is simplified by taking out not needed buttons. To play the game you need to have a Gameboy emulator installed on your smartphone.

The Gameboy was known for having a general interface for many games, in this case the main idea was to have multiple interfaces for different games. For further development can be added a “pocket” to store the diverse interfaces. It could become a “built it by yourself” artifact.
