Castle Bookends. One left and one right as I saw appropriate but it doesn't really matter which model goes with which side. I printed on a Bambu Lab P1S without supports and had absolutely no issues. If you find you're having problems with some of the overhangs, I know Orca slicer and I think Prusa slicer have a “make overhangs printable” option. This changes the geometry of the model slightly but it won't impact the end result and look.
