Give me some encouragement. Who has successfully swapped an original 3DS?

I traded 3 Switch games for a pink 3DS a few months ago. Wasn't a bad deal. Could have sold 2 for 40 and one for 30. I wasn't playing them anyways.

The pinkshell is definitely worn with a crack by the left shoulder button. It's also my least favorite color. I've shell swapped my Switch before as well as replaced the screen. I've opened up the pink 3DS to change all the buttons. I'm just worried about rolling up the ribbon cable and getting them successfully through the small hole while swapping. I have back up shoulder button ribbon cables because I've broken one before on the 3DS.

I ended up purchasing a purple shell that has a black gradient and my it finally came in after 4 weeks. I plan to do it tomorrow. I just need words of encouragement. I'm second guessing myself now. 🫠
