Harley Quinn's face as a dimensional mosaic wall hanging. Nail opening on the back side for wall hanging. Diamond and hex plates included.

I printed these with Polymaker PLA Pro Metallic, Polymaker PLA, and eSun PLA+.

Note: I wanted them as big as possible, so yes (depending on slicer version and printer) they print over the initial filament trace. It won't hurt anything, but you can always scale yours down a little and reposition, or add a pause and remove the initial trace lines.
