I print the entire chair with a .6 nozzle. The only thing I am printing with a .4 is certain custom wheels that need a thinner line width for the fine details, and the straps. I have gotten some of the straps to print with a .6 and come out good using Arachne wall instead of classic but still not consistent enough for me to go to it fully. If you open up the file for one of the custom wheels that I made, it has my .6mm profile that I use for the entire chair PETG parts. The only thing I change is for the head rest and bolt, I change those to a .2mm layer height but still print with the .6mm nozzle. Beyond that it just depends on the filament you are using. I am primarily using School House and Numakers filament which are both HS/HF so they do print a little faster than regular PETG
I re-downloaded the file from Maker World, painted on supports and slowed it down to 30mm/s and for some reason it came out fine.
I don’t know why it worked this time and not the first 10 times but it did.
I add support and a three layer raft. I set my supports at .4 when I pull it off the plate the bottom raft comes right off and it’s nice clean print
I have a positive update! This is definitely my best one yet. No rips. Thanks everyone for the suggestions!
I did:
-Support painting (I selected show overhang and painted the entire overhang area at the base. There was other overhang area and I did not paint it but I had the auto-generated tree supports enabled too)
-3 layer raft
-30mm/s on Outer Wall and Top Surface
-I attempted to check my fan settings and it was on the whole time except first layer, I think
(Additionally I have retraction off, don’t cross walls)

I also noticed this time that the dent in the M is in the file. But I got a lot less stringing in the letters this time.
Looks great. I also increased bottom layers, actually to 8. There are so many overhang walls. My last one had a small separation at the base several layers up. Thankfully it was on what would be the underside of the handle and with a soldering iron set to 235 C I was able to repair it very easy. I upped the bottom layers to 5 on both cushions also.
