Support issues printing a simple, shallow dish

I’ve had my P1S since early spring and have completed some basic projects without any real issues, just the typical learning curve. However, this stupid little dish is fighting me. It’s a cover for my window exhaust fans, and it’s about 230mm in diameter and 25mm deep (flat bottom with slightly parabolic sides). Basically, it’s like a small dinner plate. I’m using dry, PETG-HF with the same settings that I’ve used successfully many times before.

Printing it on its bottom works, but no matter what support type I pick, it uses a ton of support, and when I remove the supports the quality is awful.

See attached photo from BS and a small slice that I printed (to avoid wasting filament). I’m a bit pissed that this simple dish has me perplexed. Any ideas on how to print this properly.


If possible, I would redesign it so the underside has a steeper angle to it. Or flip it upside down and make the bottom (current top) flat.

You could also try printing it on its edge, but that would probably create its own issues.
