Title may very well be miss leading. I've installed the hard mod, all is working as it should. However, at this current time, I'm forced to hiding the sd adapter underneath back casing with some electrical tape covering the contacts. I now have the female and male JST connectors. I'm basically after some tips and some form of an idea on how modders are getting there cuts so perfect on the new 3ds xl. Are you guys using a stanley knife to achieve the perfect fit and finish?
