For enclosure, another option is a radiation shield.
What do you mean by "radiation shield"?
Looking forward to their reply!
Keeps surprising me how hard it is to find something that easy. Of course I could simply use any kind of vented enclosure, but these seem less suited for outdoor use...

But could someone tell me what causes this?
Your print head is too high: you need more "squish" on the first layer. Evidence: the print lines need to meld into one another without gaps between them and be flatter than what your picture shows. Running a calibration should fix this, though you can also do an "on the fly" adjustment if you notice it starting badly, generally when printing the skirt.
I have a Prusa 3 modded to use an all copper heatpath so that it can print faster than the stock version. An Ender 3 seems perfectly good though, and for the same money you can own more than one and parallel print.
If I were to upgrade further I'd build an enclosure to make it quieter and run some kind of hepa carbon air filter on it to minimize emissions, regardless of what brand I owned. The last I checked (around a year or so ago) there weren't any good kits for that except for one that was priced sky high for schools or corporate use.
or, when you fee comfortable with tinkering, you can build your own, with bigger print area, "nanodlp" SLA printer with cheap 2k lcd from aliex***** (possible to improve air filter and isolation, a lot more easier with less parts than building a corexy etc)
but I totally agree, when you don't need bigger print, buying a ready to use printer is simpler and the smaller lcd are just a little bit more precise
