Like others have commented, I think I spend more time tinkering or troubleshooting my Ender 3 than actually printing. I’ve had a lot of fun but it wouldn’t be my first choice.
I think I would look at the Prusa or Bamboo printers as they seem to work better out of the box.
I’m mostly focused on an msla printer these days though.
I would also love to see huge improvements in public transportation, especially around me where the last bus route leaves at 6:30 pm. The only time I would actually consider riding the bus again, it’s already shut down.
The reality, though, is that public transportation cannot replace cars for people that need them. And if you live in the United States, it’s just too damn big, and at least 20% of the population will probably never see public transportation as a viable option.
Literally dozens of them.
