STL file with a cone-shaped interal roof appears with flat roof in PrusaSliver
I have modified a 3D model in Blender to be hollow and have a cone-shaped roof so that it should be able to be printed without supports. I have exported to to STL.
However, when I load the file into PrusaSlicer, it interprets it as having a totally flat roof, which will certainly be impossible to print without supports.
Can someone explain to me what is going on? I have attached the .STL file:

There's plenty of errors in that STL, most of which Prusaslicer couldn't fix:
Having said that, it should be trivial for a Mk3S to bridge that roof, flat or not. I'd be more concerned about the sharp overhang at the top of the torso, where the head begins.

Thanks for the insight. The overhang around the torso actually prints just fine, I know because I already printed it up to the head where the cone roof begins (I was using a different, dome-type internal roof which collapsed.

Is this Any Use?

If it is, you probably need to add a brim.
What was the original model like?
Could you have loaded the solid model into Prusa Slicer, and selected 0 bottom layers and 0%infill
with maybe 3 perimeters? probably need a brim! because there is negligible surface contact on the bottom

Thanks for the fix, how did you do it?

I used Netfabb in Windows edition of Prusa Slicer, then I used Variable Layer height to reduce the layer height on the Shallow slopes.
