How to print this with out support lines.
The heart needs supports but the back side look horrible on removing the support.
I've tried Snug and grid with the results below.
My support settings are below.
Do you have any suggestions ?

Maybe split it in half then glue the two pieces together after printing?

RE: How to print this with out support lines.
I'm not really sure about what I'm looking at and the orientation of the model. But I suspect you're not going to get much better results. As Chris said, if possible you could cut the model to avoid overhangs. Or print it so that the uneven surface is out of sight. Or postprocess it by sanding.

Please post a Zipped up .3mf project file exported from PrusaSlicer, and I'll take a look and see if I can help. The .3mf file should be setup as you would when trying to print the part and will allow us to see all the settings as they pertain to the model in your project.
Note if you do not Zip the file the forum server will not allow it to be posted.

RE:
One thing to try that wasn't suggested is to use PrusaSlicer 2.4 which could possibly enhance the supported area's appearance due to the new "Thick Layer Bridges" setting that is set to OFF by default (it was the equivalent of ON before, when there wasn't a setting for this). To be 100% clear, you must keep this OFF to get the new, enhanced behaviour.
"[...] required the 1st layer objects being printed thicker than the other layers, leading to ugly object undersides. [...] Starting with this release, PrusaSlicer newly offers printing bridges and 1st object layers over supports with the default layer thickness."
Take a look at PS 2.4 Alpha 1's release notes, specifically the "Bottom layers bridges" section for more details. I'd be interested in knowing what results you get with this setting, as I didn't try it myself yet.

we did know that the OP was already using 2.4, the new bridging math works well for shorter "supported" bridging.

@swiss_cheese True. Missed the mention of snug supports in the original post. Still, might not hurt to make sure this setting is still OFF.
As suggested by @chris-laudermilk, to obtain a perfect surface I'd personally cut it in two and print flat, then glue both halves together. I think it would look alright for a shape like this.
A zipped 3mf might help figuring out a nicer way to print this as a single piece, too.

@fortinmike
I agree, I think your right, I was going to try that, and a couple other things if the OP ever posts a .3mf, not cutting but a different orientation.
I think more then just changing the bridging will help this print, different support setting as you know might also be the answer.

Here is the .3mf of the heart printed standing upright. But still the lower part has defects see these photos.
THANK YOU to everyone that posted suggestions !

OK, I tried the cut in half idea? NOT sure if it's cut in the exact middle. Can someone check or play around this this file? THANK YOU
