Tips for a new Ender owner?

So, after nearly 10 years of faithful service, my shitty ol' Wanhao i3 Plus is finally ready for retirement. Steppers are buzzing, occasional collisions with the bed, and the heat block just doesn't... heat as quickly as it used to.

Talking to a mate who does a lot more printing than I, it seems I can't pass up the Ender 3 V2. The right price for what I typically do, and is backed by a mature community.

I've ordered the auto-level kit with it, but nothing else. My i3 already sits in a Lack Rack I made, and it should comfortably take the new printer.

I have a couple of functional print projects on the backburner that were waiting for me to make a move, but wanted to get some advice on mods and upgrades first, that might make the first experience with the Ender even better.

So, asking the more experienced Ender owners out there: are there any essential upgrades, preferably 3D printed, you think I should look at first?

Cheers in advance!
