Since the crow and raven model are likely to be printed in black like I did them, they don't stand out well on a dark background.  So this is a simple circular background disk with holes provided to pass the mounting screws of the crow/raven models.  I printed it with transparent PETG (so it should withstand UV outside, or at least I hope it will….).
