I haven't maintained my Ender3 since setting it up first, then tuning it. It just keeps printing good prints forblike 4 years now. I don't even think about it, pop in the file and walk away. I don't even level the bed. Sometimes it's months between prints and it still just works. I print mostly practical parts so perfection isn't really needed but the finish has been great regardless. The only issues I have had is the bed eventually peeled up after enough PETG prints with no bed prep.
