I used your print profile printing a massive 6"x5" dust collector fitting that took 1.5 days. The profile is really slow but did good. I'm not an expert with TPU by any means. I dried it 12 hours prior and fed it into my X1C directly from the filament dryer. Interior wall has minor inconsistencies (visual). Outer wall was fine up until about 60% and then started to show the same consistency issues. Next time I'll try running the dryer during the print. Used Polymaker High Flow TPU. Thanks!
