First image with the sparse layers is s3d profile at a .25 layer I didn't change anything but remove the infill and set a single perimeter.
The Second image is .24 height, the exact same profile
I don't understand why it is putting the solid infill every 8mm
it only does this on the .25 layer setting, and I can't get my other profiles to replicate it
The infill does show in prints and the part doesn't have a shell when the infill is printed, just like the photo
