V3 contains fixes that align the throat a little better, and no longer catches the flaps randomly.

This is my take on the N64 multi region mod, the other ones I found seemed to be tricky to print, this one only needs supports under the screw holes.

Please note this only lets you play games from NTSC-U and NTSC-J regions on those region consoles. It does not make a US or Japanese console play PAL games. You would need additional mods to the system hardware to make that work.
