I own an Ender 3 V2 that I use around 10 times a year. It is one of the less sophisticated printers and still it does not require that much maintenance. You have to remove the dust, level the bed and sometimes clean or exchange the nozzle. More sophisticated printers can also do some stuff automatically (e.g. the bed leveling part).

However, the initial assembly and fine tuning took some time (approx. 1-2 hours), so I wouldn’t recommend to dis- and reassemble it all the time. If you don’t have that much space, maybe check for a small printer.

When I did my research 2 years ago the Prusa Mini was quite popular for small printer. But if you want to print big parts a lot, it might be a bit annoying as you always have to cut them into smaller chunks, print separate and finally glue them together.
