Nice work. I'm hoping to never have to do it though. I called up Nintendo about 10-11 years ago and asked them if there was anything I could do to fix the worn out stick in one of my N64 controllers. They sent me 5 of these, for free (one of them is in the controller, still going strong).

Damn, that's really generous!
Those original replacements seem to be more expensive now a days.
