This is my vision of a dragon egg. It's quite large, about 10 inches (250 mm) tall. There are 17 rows of 13 scales.
I've included three versions:
Dragon Egg = Hollow with an open bottom.
Dragon Egg _ Hollow = Hollow with a closed bottom.
Dragon Egg _ Solid = Solid egg.
I haven't tried to print this one yet. I just don't think my printer would do a good job with either the size or detail.
I'd love to see one of you out there print this.

I printed this scaled to 40%, about 100mm high. That's all my printer will handle and I didn't want to print in pieces.
I used supports just to get the large overhang at the bottom; though I'm fairly certain the print would have been okay without supports.
I painted up my print in a way that it can still glow but it has more definition. I'm not sure I like the results.
