Flag of the Heart Pirates (One Piece)

The flag of the heart pirates from one piece (Trafalgar Law's crew).

Object isn't a valid 2-manifold, so no .stl files, if anyone can help me with that, please comment.

Also includes a file with a large cylinder below it (HeartPiratesFlagBadge.scad) intended to be a badge.

Made in OpenSCAD.

UPDATE:

Added slightly improved files with the word "Debug" before the file extension, the objects in the difference function have been heightened, so they don't have to be rendered to be viewed properly (You can just use F5 now).

Object still isn't a valid 2-manifold.
