The Slytherin house crest as a dimensional mosaic wall hanging. Nail opening on the back side for wall hanging.

I printed these with Polymaker PLA Pro Metallic, Polymaker PLA Silk, and Bambu Basic 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.
