I increased the object resolution of the model so its less polygonal. Using open subdiv and crease sets to make it look nicer when it prints.
I suggest in the slicer you cut the bottom so it has enough surface area on the plate.
The original file has its scaling wrong. I fixed this and it comes into prusa slicer at the correct scale. Re uploaded after I realized the scaling was wrong in the original file.
The author remixed this model.
