Hori t5

I just got a HORI T5 stick. and I’m in the stages of putting in buttons. I think the stick is fine and doesn’t require me modding. Really the whole stick doesn’t need modding.

But I have 2x Green(CLEAR) and 2x white semitsu buttons(CLEAR) and I wanna put them to use, and have my little spin on it, but the silly part is

I can’t put my bubble top on. I mean this ball is on there TIGHT!

Anything I can use to unscrew w.o harming anything

Put a glove on, hold it tight, unscrew.

Also, open bottom and the stick should have a slot for a flat head screw. Put screw in there and unscrew.
