Sharkpad pro N64 controller knob

As the youngest of 4 siblings, I was always stuck with this controller missing its joystick; for certain games that meant an absolute disadvantage. I created this model years ago for one specific purpose, repairing this exact controller. I hope someone else can too, find satisfaction in repairing a controller rather than replacing it.It definitely fits the pictured Game Shark pro controller; likely fits genuine Nintendo controllers too. Let me know!
