Roll Out! The Transformers - Autobots & Decepticons - symbols as dimensional mosaic wall hangings.

Nail opening on the back side for wall hanging.

I printed these with Polymaker PLA Pro Metallic and Polymaker Silk PLA.

Note: I wanted them as big as possible, so yes 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.
