About this 3D model

After a few experiments with unicorn and laser etching, I remixed my previous design. Haven't made this yet, but gearing up to do so now. There are two ways to make this: Use a Unicorn pen to etch-resist a PCB Use a Laser or LaserUnicorn ( http://www.thingiverse.com/thing:6846 ) to etch a resist off a PCB
