I don't know guys. I opened the "EasterEggStamp" STL file in Cura.
The walls of the hearts are really thin and they go through the initial layers weird. So I uploaded the file to an STL repair site and got this report:
--> 0 Naked edges (?)
--> 0 Planar holes (?)
--> 0 Non-planar holes (?)
--> 1492 Non-manifold edges (?)
--> 2676 Inverted faces (?)
--> 0 Degenerate faces (?)
--> 49 Duplicate faces (?)
--> 0 Disjoint shells (?)
-> Repairing: 100.00%
----- Repair completed in 29194ms ------
-> Vertex count changed from 30339 to 27849 (-2490)
-> Triangle count changed from 63266 to 55702 (-7564)
This makes me think it's a boolean thing that occurred in Fusion. The pieces parts weren't "unioned" correctly?
@MagsE8088 the model errors aside - there are a couple settings you can look at. Make sure the "Outer Wall Inset" is 0. You might try setting the Hole Horizontal Expansion to -.1. I did get it to slice correctly like that. The image is of the "unrepaired" model with 0.2 layer height, 0.4 line width, HHE -.1.
A project file is the best to troubleshoot. If you use the "File | Save Project" command and post the 3mf file that would be good.
