The #Ender #3dprinter upgrades I would do immediately would be get rid of those stupid bed leveling wheels & setup. That is rediculous. I'd want something more permanent. The "warped" heating bed would also have to go for something of better quality. Also, "binder clips" are stupid. I'd have to go magnetic. Also, auto bed leveling with a BLTouch or whatever fancy is out there would be a must.
I was still impressed with the print quality I achieved w/o going on forever leveling the bed.
