The craftsman from the channel Shank Mods, famous for a large number of various modifications of Nintendo consoles, decided to collect joycons for Switch from the original GameCube controller. All the difficult process of preparing and manufacturing the device, he recorded in a video.
The Modder used a 3D printer during the manufacturing process, but it took several months to make it work. The WaveBird was cut in half, and mounting rails were inserted into the resulting sinuses to allow the device to slide and snap onto the Switch.
His work looks and plays almost like a standard GameCube controller. Moreover, it contains all the main features of the original joycons, including wireless connection, support for HD vibration, gyroscopes and amiibo figures.
