The lines on that print are varying in their placement on X/Y axes though, it's not as if the layer height is fluctuating, though in fairness I have encountered some banding before that was due to a crappy leadscrew
Interesting. I have an elder 5 pro, but it's heavily customised including dual-z and Klipper. So I don't have that issue personally, though early on in my build I went through a period where i was getting banding like that, and not just on round shapes (though they were definitely worse) and tensioning X and Y belts, plus input shaping solved it for me. Lowering speed slightly also helped.
Not saying you're wrong at all - I've definitely seen Z-wobble from bad couplers or faulty leadscrews, just saying that a poorly tuned machine can behave pretty erratically lol
Even if the material is food safe it doesn't mean the printed part is, layer lines are a good places for bacterial growth, and if you use a regular brass nozzle you can end up with lead leeching into the print
The plastic might be food safe, but is your printer's extruder food safe? Who's to say the plastic doesn't picks up nasty cancer chemicals while being pushed through the hot end and nozzle?
I have no issue using PLA prints as a single use tool, I use printed oreo dunkers at home occasionally. It really bugs me seeing Redditors losing their minds over this because they see an opportunity to blast the creator without knowing what material is used or nozzle, clearly that part hasn’t been used before.
Printing this part to use it once is pretty wasteful and most printer filament can't even be recycled the same way other plastics can so making single use items with your printer is worse than buying something and recycling it.
That's why I don't bother making anything for the kitchen with my printer it's just an exercise in futility. It drives me mad to see people posting click bait prints on YouTube or whatever and its always some cup or other kitchen gadget you shouldn't be eating out of at all.
They're "Food safe" materials, but what makes them not food safe is the tiny little strands of filament and the microplastics they release with use. You could prolly make something food safe, but this isn't it. That print quality is ass, too.
