This is 3 part custom button I make for customer who liked my sequencer buttons very much and wanted something similar for his project. Top part is 6mm opal acrylic which has just great diffusion/transparency ratio. Second layer is 4mm transparent acrylic spacer with big hole which help to get wider area illumination. Third layer is 4mm LED holder, and doesn`t have to be transparent. I glued 3 pieces together using superglue. Attached ZIP contains EPS file if somebody have access
