Nút Z thay thế cho tay cầm GameCube (Gamecube Z Button Replacement)

Print the Z button, I recomment SLA as I'm not sure how well some of the details would come out with FDM, but prove me wrong :)

To install, do a standard teardown, follow the prep step below, and install the printed one.

You will need to either make, or reuse a z button spring. To make a spring, a pop can worked well for me. Simply cut a piece the width of the slot, and about the length of the button. Place it in the slot, and a dab of superglue will hold it in. Bend it over (not too much, it's not as springy as the spring steel) and trim so it looks about like it does in the picture, doesn't have to be perfect.
