Hori EX-SE CANNOT OPEN HELP!

Or more accurately, I cannot get inside to remove any buttons or joystick parts because of this little bugger right here:

I understand a 7mm hex-driver is needed to remove the nut and/or washer, but how am I supposed to access it if it’s entirely surrounded with plastic?

I’m told the use of needle-nose pliers would help getting the nut loose (that doesn’t sound right) but I don’t want to risk doing any unnecessary to the weak plastic casing.

its held in there by the plastic. You don’t need to access it from the bottom. Just unscrew the top.

Yea the EX-SE’s open from the top

For the top, I think you need a 3 1/2 hex-key or just a 3.

Thanks guy, you’ve saved me many future minutes in moding my stick.
