This needs to be as strong as possible (if you like your pet). I suggest you leave it in the orientation I've put it in unless you have a good understanding of how orientation of layers affects strength. Use supports.
I printed it with 6 shells and 50% gyroid infill. It turned out a bit ugly. It'd probably look nicer with fewer shells, but I've been told shells > infill for strength, so that's what I did.
I also suggest you print it in a high temperature material (not PLA) so it doesn't soften or warp in the sun.
I take no responsibility for any harm that may come to you or your pet through use or misuse of this part.
