This is the longer-version of AeonSaber's Trigger Plug. I modified the stem of the plug to be able to comfortably seat a DH1H1 neodymium magnet. Then, I created a "stem" which fits inside the trigger, and fits the same kind of magnet. I glued in the magnets using a tiny bit of super glue. I did not need to glue the stem into the GCC trigger, as it fits very snugly.

WARNING: Once the stem is placed inside the trigger, it is unlikely you will be able to remove it. The good news is that this should not interfere with any other trigger plugs, as it sits quite deeply in the trigger and is pretty much unnoticeable.

On that note, if you do not use any magnets, this design still works as a trigger plug - all I did was add a hole to the top of the plug.

With trigger plugs, I have found that the trigger pads for my controller wear out over time, eventually puncturing completely and failing to "rebound" back to a neutral state. So, to combat this, I take the base pad and glue it to the trigger plug itself.

The result doesn't have the same "snapback" kind of feel, but with a spring, you'll still experience some resistance to return the trigger to a neutral position.

Additional note: I use a Phob and have modified my trigger to only use digital press (no analog).

I'm putting this out there in case anyone else has a similar issue. Maybe this can help alleviate the issue, even if it's just while you wait for new trigger pads.
