Hardware USA non-XL N3DS: Triwing Screwdriver too big?

[CrispyYoshi]

So the JN3DS non-XL had all-phillips screws to get to the motherboard, but I was surprised to find out that the USA non-XL N3DS uses 3 tri-screws protecting the micro sd card slot.

I tried using my generic triwing screwdriver I use for everything else (NDS, DMG-01 Gameboy, GBA SP...) but ended up realizing that the screwdriver was too big!

The screws look to be the same size as all the other phillips screws inside this USA non-XL N3DS. Does anybody know what size the screws are, and where I can get a triwing that can unscrew them? I'm looking to install a hardmod on this thing, but I can't get in without the proper screwdriver.

Thanks in advance.

EDIT2: Ordered this noticing it included two triwing sizes (1.5, 3.0). Gonna hope it works: http://www.amazon.com/Silverhill-Screwdriver-Nintendo-Wii-DS-Lite/dp/B001AHAW0K

Wow that's actually kinda bizarre, I thought they ditched those a long time ago. No idea on that size, mine were just philips.

Yeah, it's definitely bizarre! Anyway, just posting to confirm that the screwdrivers I linked in my first post was the proper size for the N3DS USA triwing screws.
