Chick-Fil-A LED Lightbox.

I used aluminum reflective tape on the inside of the box and also on the backplate. I printed mine at 120% of the file, to maximize my build plate. Here is a link to the LED's that I used.

I went around the inside of the box twice with the LED's and kept as far to the back as I could to diffuse more of the light.
