The triggers of the wireless gamecube controller by powerA has no analogue sensor for the triggers yet it still has the long travel of the original controller. This little mod shortens the travel by 3.3mm which makes it so that the trigger is always in contact with the rubber membrane of the contact switch

The peg is intentionally a loose fit as i was worried about it breaking on the inside of the trigger if it were tight, it shouldn't rattle as the rubber membrane keeps it in place. the ring piece is so that the trigger bottoms out against a piece of printed plastic instead of against the little PCB the contact is located on.

One downside about this mod is that the springs vibrate like a tuning fork when the trigger is pressed, it doesn't bother me but i see it could be annoying.

Here is the TinkerCad link if you wish to adjust it. its really just four cylinders grouped together. https://www.tinkercad.com/things/5KIV0e9Kwzo
