Hey there! I recently modded a 2DS with USB-C as a gift for my girlfriend. Thought I'd share since I couldn't find anyone online who's done something similar to what I did here!
I wanted to keep the original charger in tact since I find it ugly to see the USB-C port with a gap and found the lanyard part to be almost the right size. Used a small port I got from Aliexpress and it works perfectly!
