Download the vector files for this project from Thingiverse (Iron Man 3-inspired version available, too). Inking the engraved portion with a dry erase marker really brings out the detail. We layer two of these together for a neat 3D effect then later we'll wrap wire through the provided holes and indents to hold them together.

Hairline features are vector cuts, everything else is engraved.

Our settings, using a 60 Watt Epilog:
Raster speed 50%, raster power 50%, vector speed 40%, vector power 100%, vector frequency 5000
Have fun!
