This is the model I made for Lunafreya's brooch of her family crest.
For some reason I never finished the back of it, but it seems to print fine. Hopefully it prints okay for you too!
Have fun!
EDIT:
I have fixed up this model to make it easier to print, fix up some of the low poly sections, and made it a touch bigger than the old model. I hope that this model works better for anyone having issues printing the old one.
