Apply a triangle filter to ensure the mesh is simply polyhedral

meshfix = mf.MeshFix(mesh.triangulate())
holes = meshfix.extract_holes()

Outline the holes in the mesh

p = pv.Plotter()
p.add_mesh(mesh)
p.add_mesh(holes, color="r", line_width=8)
p.enable_eye_dome_lighting()  # helps with depth perception
p.camera_position = cpos
p.show()

Emphasize the hole near the ear - this needs to be repaired so that the mesh is absolutely water tight.

cpos_ear = [(180.0, -206.0, 17.0), (107.0, -122.9, -11.9), (-0.13, 0.22, 0.96)]

p = pv.Plotter()
p.add_mesh(mesh)
p.add_mesh(holes, color="r", line_width=8)
p.enable_eye_dome_lighting()  # helps with depth perception
p.camera_position = cpos_ear
p.show()
