This is a replacement joystick for the “NEW! 2DS XL.” However, it should be compatible with most 3DS families.

I highly recommend using resin to print this, as that's how I printed it. This needs support because it is full of cavities! Do not print without supports. If you used a fine nozzle, you could probably print it using filament; I just don't have the ability to test that. If you can test that, please let me know your results!
