2 halves glued together. 1mm top and bottom 2 parameters 25% lines infill. Overature yellow PLA, 300% on a Anycubic Chiron. 50 daylight led Christmas lights. The perfect topper for my light tree.
When I print another one, I think I will print thinner top and bottom and a single outer wall and 10% infill. I will also use some double row LED strips to light it evenly. This is a GREAT model that scales VERY well.
