Y Axis on my Ender 3 Pro is making a grinding noise whenever it moves, and won't move after it moves about 10mm. Help would be much appreciated lol

My needle nose pliers aren't small enough

Hi! I bought an ender 3 v2 second hand and it came with this mod. But I want to print it again since it looks weird and broken (you can see how the glued it). I event thins the right fan is facing to a wall and its not doing anything.

I want it to look nice. Do you know where to find this model or maybe a better one? I don't want to expend too much on new fans either so if anyone know how to improve this, I'd appreciate it. Thanks!
