My version of Flynn's sign from Tron. I used LED's from Amazon to light the project box.
10 % on the box, 100% on the colored top.
Do not Scale as it will mess up the color print levels needed to make this in color. I used Simplify 3D to slice the logo top into a print for each color printed on top of the last color printed. I printed Yellow from 0 to .4mm, Orange from .4mm to .8mm, finally Black from .8mm to 1.4mm.
