Circle pad issue possibly? Do I buy a new one

[old spruce]

3ds from 2011 I’ve had collecting dust for a few years, I found it recently and want to take it to college, but is it worth fixing this problem and modding it or just buying a whole new 3ds?

[true wolf]

I havent done it myself but ive been told this is the easiest thing to fix on these
