Labyrinth Knockers - fixed with flat backs

Remixed from Framingr's original models. Gave the option for flattened back for easier printing (they will still need support material), as well as a crude attempt at fixing the gap that Framingr inexplicably added to the right knocker.
I am not a sculptor at all, so I'm hoping someone can do a better job of making it look more organic, but the way I bridged the gap should be fine for small-medium prints. Hope someone finds it useful!
