I would imagine the one I returned got shipped back to the manufacturer or distributor, I can’t say for certain, but I’d guess most people who had such an obvious defect out of the box would do the same thing, might explain why you’ve never seen one. And, yes, I improperly lumped the poorly spec’d brass extruder gear into QA, you are correct, it was poor design. My point stands, Creality, at least from the period I bought mine, (likely manufactured during that era) had poor QA / poor design. I eventually got tired of manually trimming the bed every few prints, installed the Creality abl switch which really didn’t do much other than highlight the fact that the glass/PEI Creality beds seemed to warp on me. Once again, I’m speaking on my own experience, and if you’re new to the hobby and feel that Creality printers have improved enough to the point where they are reliable and relatively hands-off maintenance-wise, feel free to purchase one. My advice is worth exact as much as everyone else’s, one random voice on the internet.
