Ender 3 Upgrade Essentials?

Ender 3 Upgrade Essentials?
Just wondering if there are any part upgrades I may need for my Ender 3.
At the moment it is ok apart from a couple of thermal runways.

dozens. You can modify a 3 so that it has most or all of the improvements of the newer versions and then some. It is just about money and if you want to do it. My Ender 3v2 is getting to point that I don’t recognize the original printer any more.
